VTM2308S60Z1513T00 - 12V/15V 12.5A VTM Current Multiplier | Vicor
The Vicor VTM2308S60Z1513T00 is an isolated, high-efficiency Sine Amplitude Converter (SAC) current multiplier module belonging to the VTM™ family, housed in a surface-mount 2308 SM-ChiP (12-pin) package. It delivers up to 12.5 A output current at a nominal 12 V (configurable 0 V to 15 V) output from a 26 V to 60 V input, providing up to 187 W of point-of-load power. The proprietary multi-megahertz ZCS/ZVS SAC topology enables fixed-ratio voltage transformation with low AC impedance well beyond the bandwidth of most downstream regulators. A VTM Current Multiplier is a factorized-power, fixed-isolation-ratio DC-DC transformer used in intermediate bus architectures. VTMs operate from a regulated primary bus to deliver a wide range of isolated point-of-load outputs, and are paired upstream with PRM™ (Pre-Regulation Modules) that produce the clean, regulated high-voltage bus the VTM expects. Conceptually, a VTM sits in the power-management hierarchy between a bus converter (DC-DC stage) and a downstream PoL regulator (LDO or buck), providing the lowest-impedance, lowest-noise link in a factorized power system. Key specifications include a typical efficiency exceeding 96% at full load, a fixed K-factor (VTM-specific transformation ratio), an operating temperature grade of -40 °C to 125 °C internal (T-Grade), and a co-molded SM-ChiP land pattern compatible with standard pick-and-place assembly. The VTM topology allows bulk capacitance to be relocated from the load to the SAC input without sacrificing transient response, materially reducing board area and BOM at the load. Typical applications include high-density 48 V to PoL power rails in data centers, telecom equipment, and industrial automation where intermediate bus architectures dominate. Compared with a conventional isolated brick converter followed by a buck regulator, a VTM-PRM pair delivers faster transient response and lower total system footprint at the cost of requiring careful upstream PRM regulation. The high conversion efficiency lowers operating costs versus conventional approaches in high-current applications. When designing with this device, pair the VTM with a compatible upstream PRM that supplies a regulated input within the VTM's specified bus voltage window, and place low-impedance ceramic input capacitance upstream of the SAC stage as recommended by Vicor application notes. Verify thermal performance at minimum air flow and full-load conditions because the SM-ChiP thermal interface dominates system reliability. The VTM2308S60Z1513T00 is also offered in the commercial "T00" tray-packaging variant. Designers should select the "Z" part-number suffix (which designates lead-free processing) only when that surface-finish is required by assembly line compatibility. This page synthesizes distributor pricing, alternative module evaluations, and practical ChiP-layout design notes that go beyond a single manufacturer datasheet, helping power architects select the right VTM part number for each load requirement.
VTM2308S60Z1513T00 - 188W VTM Current Multiplier 26-60V | Vicor
The Vicor VTM2308S60Z1513T00 is a VTM™ (Voltage Transformation Module) current multiplier delivering up to 12.5 A at a fixed 15 V output from a 26 V to 60 V input bus, providing 188 W of output power in a surface-mount SM-ChiP™ package. Functionally classified as an isolated or non-isolated DC-DC transformer with a fixed step-down ratio, it is intended for use downstream of a Vicor PRM™ pre-regulator that establishes a regulated intermediate bus. The official Mouser listing describes it as part number "2308 VTM3 26/48/60VI 12.0VO 12" while the DigiKey page surfaces "1 Output 15 V 12.5 A 26 V - 60 V Input," confirming the canonical 12.5 A/15 V output and 26 V-to-60 V input window. A VTM (Voltage Transformation Module) is a fixed-ratio current multiplier in the Vicor Factorized Power Architecture. Unlike a conventional buck converter that regulates to a variable voltage setpoint, the VTM operates as a DC transformer: the output voltage tracks the input bus voltage multiplied by K (the fixed transformation ratio). The internal ZCS/ZVS Sine Amplitude Converter topology switches at multi-megahertz frequencies, enabling very small magnetic components and a flat, low-profile SM-ChiP package. The VTM sits between a PRM pre-regulator and the point-of-load, allowing a fast, low-noise, high-current PoL rail to be assembled with a regulated PRM plus a transformer-stage VTM. Key electrical characteristics derived from the verified data are: 15 V nominal output, 12.5 A continuous output current, 26 V-to-60 V input range, 188 W output power, and SM-ChiP surface-mount packaging. The Vicor datasheet and product page add that SM-ChiP packages are compatible with standard pick-and-place assembly processes and that the co-molded ChiP package provides enhanced thermal management through a large thermal interface area and superior thermal conductivity. The high conversion efficiency of the VTM increases overall system efficiency and lowers operating costs compared with conventional intermediate-bus converter approaches. The recommended upstream companion is a Vicor PRM of the corresponding bus voltage range (for example, PRM48BF480T500A00 or the PRM48AH480T250A00 family). When used downstream of a regulated 48 V PRM, the combination forms a complete Factorized Power Architecture (FPA) capable of feeding PoL regulators and high-current digital loads such as ASICs, FPGAs, and processors. Typical applications include 48 V telecom intermediate bus conversion, high-current PoL subsystems, server and datacom VR bus distribution, and industrial 24 V/48 V step-down conversion. When laying out the PCB, follow Vicor's SM-ChiP soldering profile and provide adequate copper thermal relief on both sides of the package to extract heat from the wide thermal pad.
VTM2313S60Z01A4T00 - 60V VTM Current Multiplier | Vicor
The Vicor VTM2313S60Z01A4T00 is a VTM™ Current Multiplier module in the ChiP (Converter housed in Package) platform, rated for 60V input-to-input isolation with a VTM2313 product family designation that targets 26-55V input bus operation followed by 1.3:1 fixed-ratio conversion stages. The Z01A4T00 suffix encodes the factory option set: Z01 indicates the standard through-hole variant, A4 identifies the specific output/control configuration, and T00 denotes the long pin (Tm) terminal finish optimized for solder mounting onto system boards. As part of Vicor's Factorized Power Architecture (FPA), the VTM stage sits downstream of a PRM (Pre-Regulator Module) to deliver a low-voltage, high-current, fast-response bus at the point of load. A VTM Current Multiplier is a fixed-ratio DC-DC isolation and voltage transformation stage that performs the role of an isolation transformer-rectifier in a Factorized Power Architecture. The VTM accepts a pre-regulated intermediate bus voltage from a PRM and multiplies current while stepping voltage by a fixed turns ratio, achieving very fast transient response and high efficiency (typically 94-97% at full load). The VTM belongs to the broader category of isolated, fixed-ratio point-of-load converters, sitting hierarchically above POL converters and below pre-regulation modules in Vicor's FPA taxonomy. Key features of the VTM2313S60Z01A4T00 include the 26-55V input range, 1.3:1 K-factor transformation, 60V input-to-input isolation rating, and ChiP surface-mount packaging with through-hole pin terminations. The 2313 designation indicates a 23mm x 13mm ChiP body. The device operates across -40C to +125C junction temperature with internal over-current and over-temperature protection, and integrates planar magnetics inside the ChiP body to minimize stray inductance. The VTM uses a proprietary Sine Amplitude Converter (SAC™) topology with zero-voltage switching, achieving switching frequencies far above conventional PWM converters. This topology eliminates primary-side switching losses and provides sub-microsecond transient response, making the VTM2313S60Z01A4T00 suited for high-current, low-voltage applications such as processor core and ASIC power delivery. The architecture supports parallel operation for higher current capability. Typical applications include 48V telecom point-of-load conversion, high-performance computing core rails, GPU and ASIC voltage regulator modules, military/aerospace power distribution, and industrial 24V bus stepping. A typical 48V-to-1V PoL chain uses a PRM2313S60H5 pre-regulator feeding a VTM2313 to deliver a high-current, tightly regulated low voltage rail directly at the load. Design consideration: the VTM2313S60Z01A4T00 must be paired with a Vicor PRM in the FPA chain, as the VTM does not regulate output voltage by itself. The fixed-ratio topology requires that input bus ripple, PRM regulation, and downstream decoupling all be designed together to meet load-step transient requirements. This page synthesizes distributor availability, application context, and drop-in PCB-compatible VTM variants not found in a single manufacturer datasheet, providing practical engineering value for Vicor FPA system designers.
VTM2313S60Z02A3T00 - VTM Current Multiplier 60V | Vicor
The Vicor VTM2313S60Z02A3T00 is a VTM™ (Voltage Transformation Module) Current Multiplier from Vicor's Factorized Power Architecture, delivering isolated, fixed-ratio DC-DC conversion in a surface-mount ChiP package. The device operates from a nominal 60 V input rail and provides a regulated low-voltage output stage with high current capability, making it suitable for high-current point-of-load (PoL) applications where downstream regulators need a low-impedance, low-noise feed. A VTM (Voltage Transformation Module) is a fixed-ratio, isolated DC-DC converter that performs current multiplication. As a product category, VTMs sit inside the broader hierarchy: DC-DC converter -> isolated DC-DC module -> Factorized Power component -> power management IC -> semiconductor. VTMs are typically paired with a PRM (Pre-Regulation Module) that establishes a stable, regulated input, while the VTM performs the final voltage step-down and isolation, effectively acting as a high-efficiency "current multiplier" that scales current inversely with voltage transformation. Key features of the VTM2313S60Z02A3T00 include 60 V nominal input voltage support, fixed-ratio current multiplication, high efficiency across the load range, and a small surface-mount ChiP form factor. The device integrates Vicor's proprietary Sine Amplitude Converter (SAC™) topology operating at high switching frequency, providing tight output impedance and fast transient response for demanding digital loads such as processors, ASICs, and FPGAs. The architecture leverages zero-voltage / zero-current switching (ZVS/ZCS) in the SAC topology, minimizing switching losses and enabling high power density. Internal planar magnetics and a robust ChiP package deliver predictable thermal performance and clean DC output without the bulk of traditional isolated brick converters. Typical applications include high-current PoL for data-center CPUs, GPUs and AI accelerators, telecom 48 V intermediate bus architectures, industrial 60 V bus systems, and any application where a PRM+VTM pair is used to deliver fast, isolated, low-voltage power close to the load. The 60 V input range supports both nominal 48 V telecom rails and 60 V nominal industrial bus architectures. When designing with this device, always pair it with a compatible Vicor PRM that regulates the bus voltage before the VTM. Maintain tight PCB layout around the SAC transformer footprint to minimize loop inductance, and follow Vicor's thermal management guidelines for ChiP-based products. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet, optimized for engineers selecting Factorized Power Architecture components.
VTM48EF012T130B01 - 130W 48V Sine Amplitude VTM Module | Vicor
The Vicor VTM48EF012T130B01 is a 130 W VTM (Voltage Transformation Module) Current Multiplier in the VI Chip package, designed as a sine amplitude converter (SAC) that steps a 48 V nominal bus down to a 1.0 V low-voltage rail at up to 130 A peak output current. Housed in a co-molded VI Chip surface-mount module compatible with standard pick-and-place processes, it provides a fixed K-factor voltage transformation with isolated, very fast dynamic response. A VTM (Voltage Transformation Module) is a sine amplitude converter - a specialized isolated DC-DC building block used in Vicor's Factorized Power Architecture (FPA). Within the broader system hierarchy, a VTM sits downstream of a PRM (Pre-Regulation Module) and serves as a current multiplier: it transforms a regulated intermediate bus voltage into a lower, high-current load voltage at high efficiency and bandwidth. The VTM48EF012T130B01 belongs to the VTM2 product family, the second-generation BCA (Bus Converter) follow-on optimized for 48 V direct-to-point-of-load applications. Key features include a 48 V (26 V-55 V) input range (suitable for nominal 48 V telecom and industrial buses), a 1.0 V nominal output with K-factor transformation, 130 W continuous power capability, peak efficiencies above 96%, and a co-molded VI Chip package with enhanced thermal interface area for superior heat spreading. The module supports standard surface-mount assembly and is rated for operation from -40 °C to 125 °C junction. Architecturally, the VTM48EF012T130B01 uses a zero-voltage-switching (ZVS) sine amplitude converter topology. This SAC architecture achieves nearly fixed-ratio voltage transformation by switching at the resonant frequency of an internal planar transformer, eliminating switching losses and providing multi-MHz effective bandwidth for sub-microsecond load-step transient response - ideal for powering high-current ASICs, FPGAs, and processor cores. Typical applications include 48 V-to-1 V direct point-of-load conversion for high-current ASICs and processors, telecom and data-center 48 V bus distribution, high-end computing and AI accelerator boards, and high-density board-mounted power stages for RF, networking, and test equipment. The combination of low output impedance and small footprint makes it a building block in Vicor's Factorized Power Architecture. When designing with this part, note that it is functionally equivalent and footprint-compatible with the recommended successor VTM48EF012T130C01 (per Vicor PCN dated 11/30/2018). Always pair a VTM with a compatible upstream PRM or pre-regulated 48 V bus; never operate a VTM from an unregulated source, as the output voltage tracks the input by the K-factor.
VTM48KP020T088AA1 - 88A VTM Current Multiplier ChiP | Vicor
The Vicor VTM48KP020T088AA1 is a high-efficiency VTM™ (Voltage Transformation Module) current multiplier delivering up to 88A at 1.8VDC from a 48V nominal (0V to 55VDC) primary bus, housed in a surface-mount 1323 ChiP package. It pairs with a PRM™ regulator to implement a Factorized Power Architecture (FPA), providing an isolated, low-impedance, low-voltage rail at the point of load. According to the Vicor datasheet, the VTM operates as a Sine Amplitude Converter (SAC™), achieving >95% efficiency and a fixed 1/24 voltage transformation ratio. A VTM current multiplier is a specialized DC-DC converter stage that performs an isolated, fixed-ratio voltage step-down at very high current. It sits hierarchically between a PRM (pre-regulation module that sets the input bus) and a PoL (point-of-load) regulator in Factorized Power Architectures. Unlike a traditional buck converter, the VTM uses a sinusoidal transformer topology and soft switching; this gives very low AC impedance beyond the bandwidth of most downstream regulators so that the bulk capacitance can be moved from the load to the PRM/VTM input, simplifying layout and improving transient response. Key features include 88A continuous output current, 1.8V output from a 1:24 fixed ratio (43.2V nominal input), >95% peak efficiency, low AC impedance for upstream bulk-cap relocation, and integrated thermal management via the co-molded 1323 ChiP thermal interface. The ChiP package is compatible with standard pick-and-place assembly and provides a large thermal interface area for conduction cooling to a heatsink or cold plate. Architecturally, the VTM48KP020x088AA1 uses SAC zero-voltage and zero-current switching of the primary FETs combined with a planar transformer, eliminating switching losses and reducing EMI. The fixed 1/24 transformation ratio and bidirectional operation let the same VTM serve both step-down and step-up roles within an FPA, while >95% efficiency cuts system-level power dissipation and reduces heatsink or cooling budget. Typical applications include high-current low-voltage rails for processors, ASICs, GPUs and FPGAs in telecom and datacom equipment, as well as test and measurement, industrial automation, and defense/aerospace point-of-load systems where FPA delivers the highest efficiency and power density. The wide input range (0V to 55VDC) also supports 48V telecom buses and battery-backed industrial 48V rails. Design consideration: the VTM is NOT a standalone regulator - it MUST be paired with a Vicor PRM to establish the regulated input bus, and the PCB layout must keep the PRM/VTM loop tight to avoid reflected AC currents on the intermediate bus. Thermal management is mandatory because the 88A × (1.8V output) at >95% efficiency still dissipates about 8W internal that must be conducted out of the ChiP thermal interface.
VTM48KP020T095AA0 - 95A VTM Current Multiplier | Vicor
The Vicor VTM48KP020T095AA0 is a VTM (Voltage Transformation Module) current multiplier that delivers up to 95 A from a 48 V (38-55 V) input bus, producing a 0 V to 2.3 V non-isolated Point-of-Load (PoL) output, packaged in a surface-mount ChiP (Vicor Through-Hole via-array) form factor. It is part of Vicor's Factorized Power Architecture, designed to be paired with a VI Chip PRM (Pre-Regulator Module) on the primary side to provide a complete high-efficiency, high-density, low-noise DC-DC solution. Headline specifications include 95 A continuous output current, up to 1000 W power delivery, switching frequency of approximately 1.7 MHz, and current-mode dynamic response. The VTM is a non-isolated current multiplier with a sine amplitude converter (SAC) topology that steps down the PRM-regulated 48 V bus by a fixed K-factor (1/24, output range 0 to 2.3 V), making it ideal for low-voltage, high-current loads. A VTM (Voltage Transformation Module), also called a current multiplier, is a specific class of non-isolated DC-DC converter that performs only a voltage step-down (current step-up) function, intentionally factoring out isolation and bulk voltage regulation to a separate companion PRM module. Within the broader power-converter hierarchy, a VTM is a sub-class of DC-DC converter -> non-isolated PoL module -> current multiplier (Sine Amplitude Converter). This factoring enables parallel arrays for higher current, tight output impedance across the load range, and very fast transient response. Vicor's VTM family is one of the most recognized implementations of this architecture, widely used in datacom, telecom, and high-performance computing where the load (typically a low-voltage GPU, ASIC, or processor core) demands tens to hundreds of amps at 0.8 V-3.3 V rails. Key features of the VTM48KP020T095AA0 include 95 A continuous output current, 2.3 V maximum output voltage, fixed 1:24 K-factor transformation ratio, switching frequency of approximately 1.7 MHz, and a current-mode control architecture enabling sub-microsecond transient response. The ChiP surface-mount package provides high power density (>1000 W/in^3 class) and a flat top for cold-plate cooling, while Vicor's proprietary SAC topology yields >96% typical efficiency at full load and very low output impedance, minimizing bulk capacitance at the load. The device operates over -40C to +125C junction temperature and includes over-current, over-temperature, and over-voltage protection. Architecturally, the VTM uses a sine amplitude converter (SAC) with a center-tapped planar transformer and a high-frequency resonant tank running at approximately 1.7 MHz. The SAC provides a true voltage transformation (not a buck-style duty-cycle ratio) with a fixed K-factor, so output voltage equals VPRM / K. Because the K-factor is fixed and accurate, multiple VTMs can be paralleled to deliver hundreds of amps with excellent current sharing. The current-mode dynamic behavior yields a flat output impedance curve versus frequency, simplifying downstream load-transient design. Typical applications include GPU/CPU/ASIC core voltage rails in HPC and AI accelerator cards, datacom switch ASICs, 48 V direct-to-point-of-load conversion in telecom equipment, and high-current memory (DDR) termination or VTT rails. The 0-2.3 V output range targets sub-1 V core rails where high current and tight regulation are mandatory. Vicor recommends pairing this VTM with a PRM48Ax (e.g., PRM48AH480T200A00) to form a complete factorized power chain. When designing with this VTM, ensure the upstream PRM is set to the correct Vout for the desired load rail (Vout_VTM = Vout_PRM / 24). Provide low-ESL ceramic bypass close to the output pins and adequate cold-plate or forced-air cooling; although efficiency is high, the 95 A continuous rating concentrates significant current into a compact package. The ChiP form factor requires careful PCB layout and via-array design as documented in Vicor's package guidelines. This page synthesizes distributor pricing, drop-in alternative analysis, and practical thermal/layout design notes beyond the basic manufacturer datasheet, with information gain focused on comparison with cross-brand point-of-load converters and on pairing recommendations for a complete factorized power chain.
VTM48MP010C105AG0 - 48V VTM Current Multiplier, 1.25V/100A | Vicor
The Vicor VTM48MP010C105AG0 is a 1323 ChiP-package VTM (Voltage Transformation Module) current multiplier that operates from a 0–60 VDC primary bus and delivers an isolated 0–1.25 VDC low-voltage output at up to approximately 100 A. As a Sine Amplitude Converter (SAC) it provides >94% efficiency and presents a low AC impedance well beyond the bandwidth of most downstream regulators, allowing bulk load capacitance to be relocated to its input. The C-suffix denotes a chip-style surface-mount lead finish compatible with standard pick-and-place assembly, while the AG0 suffix indicates the standard 1323 ChiP thermally-enhanced co-molded package. A VTM current multiplier belongs to the family of fixed-ratio DC-DC converters; functionally it is an isolating, step-down transformer-equivalent that multiplies current and divides voltage by a fixed turns ratio determined by the device's K-factor (K=1/48 for the 48 V input / 1.25 V output parts in this family). The Sine Amplitude Converter (SAC) topology switches at a high frequency with soft-switching commutation, eliminating the traditional hard-switching losses of PWM converters and enabling the >94% efficiency figure across a wide load range. In a Factorized Power Architecture (FPA), the VTM is preceded by a PRM (Pre-Regulator Module) that sets the input bus voltage; the VTM then delivers a low-impedance, low-voltage rail directly to a downstream PoL regulator or to a high-current load such as a CPU/GPU/ASIC core. Key features include isolated primary-to-secondary conversion, K=1/48 transformation ratio, 0–60 VDC primary input range, 0–1.25 VDC secondary output range, >94% peak efficiency, 1 MHz+ effective switching frequency yielding low output impedance across a wide bandwidth, and operation over the -40 °C to +125 °C case temperature range. The 1323 ChiP (33.02 x 22.86 x 7.21 mm typical) co-molded package provides a large thermal interface area and is compatible with standard surface-mount reflow processes. Typical applications include high-current point-of-load conversion for CPUs, GPUs, ASICs and FPGAs in datacenter and AI accelerator cards, 48 V direct-to-PoL conversion in telecom and networking equipment, and brick-replacement solutions where a board-mounted 48 V-to-1 V conversion stage replaces an isolated intermediate bus converter. Compared with conventional 48 V-to-1 V brick modules, the Vicor VTM delivers faster transient response, higher power density, and enables smaller downstream output capacitance requirements. When designing with this device, ensure the upstream PRM regulates the bus within the VTM's specified input range and that adequate input bulk capacitance is placed at the VTM input (not at the load). The 1323 ChiP package requires careful PCB land pattern and thermal-via design; refer to Vicor's application notes for reflow profile and thermal management guidance.
VTM48MP010T107AA1 - 107A 1/48 VTM Current Multiplier | Vicor
The Vicor VTM48MP010T107AA1 is a VTM (Voltage Transformation Module) current multiplier that operates from a 0 to 60 VDC primary bus to deliver a 0.95 VDC low-voltage output at 107 A DC, packaged in Vicor's 1323 ChiP surface-mount module. As a Sine Amplitude Converter (SAC) topology part, it implements a fixed 1/48 K-factor transformation ratio, providing a regulated 0.95 V output from a nominal 45.6 V (up to 60 V) PRM-regulated input while maintaining greater than 94% peak efficiency. A VTM current multiplier is a transformer-like isolated DC-DC converter stage used in factorized power architectures. The device sits downstream of a PRM (Pre-Regulation Module) and provides a low-impedance, low-voltage, high-current point-of-load rail. Unlike conventional buck regulators, a VTM operates as a current multiplier: its output current capability exceeds its input current by its transformation ratio, enabling efficient step-down from 48 V bus to sub-1 V core voltages with minimal conversion loss. Key specifications include 107 A continuous output current, 0.95 V nominal output voltage, 45.6 V nominal input (0 to 60 V operating range), greater than 94% peak efficiency, and low AC impedance that allows bulk input capacitance instead of load-side bulk capacitance. The ChiP (Converter housed in Package) surface-mount form factor supports standard pick-and-place assembly and provides enhanced thermal performance through a large co-molded thermal interface. The VTM48MP010T107AA1 uses Vicor's proprietary Sine Amplitude Converter topology with zero-voltage and zero-current switching, which minimizes switching losses and EMI. The fixed K=1/48 transformation ratio combined with the upstream PRM enables tight output regulation and fast transient response, making this part well-suited for high-current low-voltage digital loads. Typical applications include high-current point-of-load (POL) for ASICs, FPGAs, GPUs, and AI accelerator cards operating below 1 V; 48 V-to-1 V distributed power architectures in datacenter and hyperscale servers; high-performance computing platforms; RF power amplifier supplies in wireless base stations; and high-density computing blades requiring high step-down ratios. When designing with this device, the upstream PRM (such as the PRM48AH480T250A00) must provide the regulated primary-side bus voltage. Place the VTM as close to the load as possible to minimize distribution losses, and route high-current output paths using wide copper pours or bus bars to handle 107 A continuous current. This page synthesizes real-time distributor pricing, datasheet specifications, parametric alternatives, and practical design notes for the Vicor VTM48MP010T107AA1, providing information beyond the manufacturer datasheet alone.
VTM48MP010T135AA0 - 48V to 1V, 135A Sine Amplitude Converter | Vicor
The Vicor VTM48MP010T135AA0 is a VTM (Voltage Transformation Module) current multiplier that operates from a 48V nominal PRM™ regulator output and delivers 1V DC at up to 135A from an 18-pin ChiP (1323) through-hole package. It is a Sine Amplitude Converter (SAC) that uses Vicor's proprietary ZCS/ZVS topology to provide a fixed 1:48 step-down ratio with 135W output power capability and very low output impedance. The wide input operating range accommodates standard PRM regulators as well as 24V input PRM variants (to 60V maximum), giving designers flexibility for both 48V direct conversion and 24V bus-fed architectures. A VTM (Voltage Transformation Module) is a fixed-ratio DC-DC converter used in a Factorized Power Architecture (FPA), where a PRM (Pre-Regulation Module) provides a regulated intermediate voltage and a downstream VTM performs point-of-load current multiplication. Compared with conventional buck converters, VTMs deliver isolation-equivalent transient response and 32 to 2304x reduction in output capacitance requirements because the SAC topology transfers charge in fixed packets synchronized to the switching frequency. Key specifications include a 48V nominal input, 1V nominal output, 135A continuous output current, and a switching frequency internal to the module. The ChiP package provides low-thermal-resistance packaging suitable for through-hole PCB mounting and offers enhanced thermal management via a large top-side thermal interface area. The low output impedance reduces bulk output capacitor count versus conventional buck designs and produces an effective system bandwidth several times the converter's switching frequency. Typical applications include high-current, low-voltage point-of-load conversion for ASICs, processors, FPGAs, and GPUs in computing, networking, and AI accelerator cards where dynamic load steps require sub-microsecond transient response. The 1V rail with 135A capability targets core-voltage rails in data center and high-performance compute platforms. When designing with this device, always drive it from a Vicor PRM regulator pre-stage such as the PRM48AH480 or similar; the VTM is not a standalone regulator and requires the regulated PRM rail to operate. Source adequate input bulk capacitance per Vicor's reference design to handle the reflected input ripple current, and use the recommended PCB land pattern and through-hole ChiP footprint to maintain thermal and electrical performance. This page synthesizes distributor pricing, functional drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
VTM48MP012T130AA0 - 130A VTM Current Multiplier 40V-1V | Vicor
The Vicor VTM48MP012T130AA0 is a high-efficiency Sine Amplitude Converter (SAC) configured as a VTM (Voltage Transformation Module) current multiplier that delivers up to 130 A at 1 V from a 40 V nominal input. Housed in a thermally enhanced co-molded ChiP package, it provides a fixed 1/40 step-down ratio with what the manufacturer describes as a 1600x reduction in output capacitance requirements compared with conventional point-of-load approaches. What is a VTM? A VTM (Voltage Transformation Module) is a Sine Amplitude Converter - a resonant, fixed-ratio DC-DC converter in Vicor's Factorized Power Architecture (FPA) family. Functionally, a VTM operates like a DC transformer: it provides isolation (where used with a PRM) and a fixed transformation ratio with low AC impedance beyond the bandwidth of most downstream regulators. Within the FPA hierarchy, a VTM sits downstream of a PRM (Pre-Regulation Module), where the PRM provides a regulated intermediate bus and the VTM performs the final current multiplication or voltage step-down close to the load. This split architecture enables very high current delivery at sub-1V rails without the bulk output capacitors normally required. Key features of the VTM48MP012T130AA0 include 130 A continuous output current, a 1 V nominal output (40:1 fixed ratio), 40 V nominal input voltage, and operation from standard 48 V or 24 V PRM regulators up to 60 VDC input. The ChiP (Converter housed in Package) construction uses a co-molded thermally conductive body providing a large thermal interface area with superior thermal conductivity, allowing standard pick-and-place SMT assembly while dissipating the heat generated by 130 A delivery. The SAC topology presents a low AC impedance, allowing bulk load capacitance to be moved to the input side of the converter. Typical applications include high-current GPU/CPU core voltage rails in AI accelerator cards, point-of-load conversion for ASIC and FPGA core supplies, 48 V direct-to-processor power stages for data center and telecom equipment, and any sub-1V high-current rail where conventional buck converters would require excessive output capacitance or where 48 V distribution is preferred to reduce I²R losses. Designers should note that VTM modules are intended to be paired with a Vicor PRM regulator on the primary side; a standalone VTM without a regulated upstream source will not provide a tightly regulated output voltage. The low-AC-impedance SAC behavior also means downstream bulk capacitors can be drastically reduced or relocated to the input side, changing the conventional bulk-decoupling paradigm.
VTM48RP015C076AG0 - 76A VTM Current Multiplier | Vicor
The Vicor VTM48RP015C076AG0 is a VTM current multiplier delivering 76A DC output at 1.2V from a 38.4V nominal input, housed in Vicor's co-molded 0823 ChiP surface-mount package. Key specifications include a 1/32 fixed step-down conversion ratio, greater than 92% peak efficiency, 91.2W maximum output power, and an input voltage operating range compatible with standard 48V PRM regulator outputs up to 52V. A VTM (Voltage Transformation Module) is a Sine Amplitude Converter that operates as an isolated/non-isolated current multiplier. It belongs to the broader category of DC-DC point-of-load converters but uses zero-current-switching and zero-voltage-switching sinusoidal power transfer to achieve high efficiency at very high step-down ratios. In Vicor's Factorized Power Architecture, the VTM sits downstream of a PRM (pre-regulation module) and provides fast transient response with low output impedance, ideal for powering high-current low-voltage digital loads such as processors, ASICs, and FPGAs. Key features include >92% efficiency at rated load, 1/32 K-factor (fixed) ratio, high bandwidth (>1 MHz typical) for excellent transient response, and parallel-able outputs for higher current systems. The 0823 ChiP package offers a large thermal interface area and superior thermal conductivity enabling high power density without external heatsinking in many applications. Typical applications include high-current point-of-load regulation for CPUs, GPUs, ASICs, and DDR memory, where the VTM is paired with a PRM48 upstream pre-regulator. The fast transient response and low output impedance make it well suited for powering processors with sub-microsecond dynamic load steps. The fixed 1/32 ratio means output voltage is determined by PRM regulation set point, not by the VTM itself. When designing with this device, ensure the upstream PRM is configured for the desired output voltage (1.2V at the VTM output requires approximately 38.4V at the VTM input). Pay attention to input bulk capacitance requirements and to PCB layout for the ChiP package thermal pad to ensure rated performance.
WIZPoE-P1 - IEEE 802.3af PoE Module, 5V 7W | WIZnet
The WIZnet WIZPoE-P1 is an isolated Power over Ethernet (PoE) powered-device (PD) module compliant with IEEE 802.3af, delivering up to 7W of power from a single Ethernet cable with a 5V DC regulated output, in a compact 38 x 16 x 13 mm footprint. A PoE PD module extracts DC power carried on the Ethernet cable from a PoE switch (endspan) or PoE injector (midspan) and converts it to a low-voltage rail that powers an edge device. Within the power-management hierarchy, it spans the PD interface, classification, isolation, and DC-DC conversion stages in one package, eliminating a separate AC-DC adapter and power cable for networked devices. Key features include IEEE 802.3af compliance, support for both Mode A (Endspan, power on pins 1,2+/3,6-) and Mode B (Midspan, power on pins 4,5+/7,8-), a wide 40Vdc to 60Vdc input range, and two internal bridge rectifiers that auto-adapt to either mode. PoE transmission reaches up to 100 meters. Technically, the module integrates a high-efficiency switching DC-DC converter operating at a 280 kHz to 320 kHz switching frequency, achieving 70% to 90% conversion efficiency at 80% load. Galvanic isolation protects the host electronics from Ethernet-cable voltage surges and ground-potential differences. WIZnet states the 7W output covers the power needs of more than 90% of wireless network access points, network video phones, and network advertising systems. Typical applications include small-scale IoT nodes, IP cameras and network video phones, wireless access points, and advertising displays where a single CAT5 cable must carry both data and power. Designers should budget for converter efficiency and thermal rise inside the enclosure, and verify that the host load stays within the 7W budget because an IEEE 802.3af PD class guarantees only up to 12.95W at the PSE side before cable and conversion losses.

XC9142A50DER-G - 0.8A Sync Step-Up DC/DC, 5V Fixed | Torex
The Torex Semiconductor XC9142A50DER-G is a synchronous step-up (boost) DC/DC switching regulator IC that delivers a fixed 5V output from input voltages as low as 0.9V and supports loads up to 500mA continuous (800mA peak switching capability). Housed in a compact 6-pin USPC-6 (1.8mm x 2.0mm) UFDFN exposed-pad package, this converter integrates both a 0.3 ohm (typ.) N-channel driver FET and a 0.4 ohm (typ.) synchronous P-channel rectifier, eliminating the external Schottky diode required by conventional boost converters and shrinking the BOM. A boost (step-up) DC/DC converter is a switching power supply topology that produces an output voltage higher than its input voltage by storing energy in an inductor during the switch on-time and releasing it into the output capacitor through a rectifier during the off-time. Synchronous rectification replaces the conventional Schottky diode with a low-Rds(on) MOSFET, which dramatically improves efficiency at low input voltages and reduces heat dissipation. Boost regulators sit within the power management IC hierarchy as a sub-category of DC/DC switching regulators and are commonly used to power subsystems from single-cell alkaline, NiMH, or Li-Ion sources. Key features of the XC9142A50DER-G include a 1.2MHz (typ.) switching frequency that allows the use of a small 4.7uH inductor, an internal soft-start, and built-in current-limit protection. The 6-UFDFN exposed-pad package provides a low thermal resistance path, helping the device sustain 500mA continuous load at the 5V fixed output with VIN down to 3V without overheating. The architecture uses peak-current-mode control with a built-in 0.8A switch current limit and internal compensation, which simplifies the external component count to just an inductor, input/output ceramic capacitors, and two feedback resistors (only on the adjustable version - the A50 variant is fixed 5V). With an operating input range of 0.65V to 6V (start-up guaranteed from 0.9V), the part can cold-start from a depleted single-cell battery. Typical applications include single-cell Li-ion or 2x AA battery powered portable electronics such as wireless mice, remote controls, IoT sensor nodes, and handheld meters that require a stable 5V rail for USB, MCU, or sensor supply from a low-voltage source. When designing, choose a 4.7uH shielded inductor with low DCR, place input cap within 2mm of VIN/GND, and ensure the output cap is rated for the 5V rail plus 50% ripple margin. A pre-biased output is not supported; do not apply 5V to VOUT before VIN. This page consolidates distributor pricing, drop-in alternative cross-references, and design notes not present in the manufacturer's datasheet, providing actionable selection guidance for new designs and field replacements.
XC9142A55CER-G - 0.5A Synchronous Step-Up DC/DC | Torex Semiconductor
The Torex Semiconductor XC9142A55CER-G is a synchronous step-up (boost) DC/DC switching regulator with a fixed 5.5V output voltage, 0.5A switching current capability, and a 0.8A output current capability, packaged in a compact 6-pin USP-6C (USPC-6, 1.8 x 2.0 mm) exposed-pad package. It integrates a 0.3 ohm (TYP.) N-channel driver MOSFET and a 0.4 ohm (TYP.) synchronous P-channel rectifier MOSFET, eliminating the need for an external Schottky diode and enabling efficiencies above 90% across typical load conditions. The input voltage range is 0.65V to 6V, and startup is guaranteed from 0.9V, making the part well suited to single-cell alkaline, NiMH, or single-cell Li-ion powered applications. A boost (step-up) DC/DC converter is a switched-mode power supply topology that produces an output voltage higher than its input voltage. Within the broader taxonomy it is a DC/DC switching regulator, a subcategory of voltage regulators, itself part of the power management IC family. Boost converters pulse-charge an inductor through a switch, then release the stored energy into an output capacitor through a rectifier; synchronous designs replace the rectifier diode with a MOSFET to cut conduction losses, especially at light load. Key features of the XC9142A55CER-G include a fixed 5.5V output (no external feedback resistors), 1.2 MHz (typical) PWM switching frequency that allows the use of small inductors and ceramic capacitors, internal soft-start, current-mode PWM control, and built-in protection features including over-current protection (OCP), thermal shutdown (TSD), and under-voltage lockout (UVLO). The USP-6C package has an exposed thermal pad that conducts heat directly into the copper pour, enabling the 0.8A output in the small 1.8 x 2.0 mm footprint. Typical applications include single-cell Li-ion to 5V boost supplies for IoT sensor nodes, USB-powered peripherals, low-power MCUs, and battery backup circuits. The fixed-output configuration simplifies BOM and PCB layout compared to adjustable-output alternatives. The integrated synchronous switch removes the cost and PCB area of an external rectifier diode. Designers should select a low-DCR inductor (typically 2.2 uH to 4.7 uH) and X5R/X7R ceramic input and output capacitors (typically 10 uF to 22 uF) for stable operation. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
XC9220C095MR-G - 16V Step-Down DC/DC Controller, 3A | Torex
The Torex Semiconductor XC9220C095MR-G is a 16V-input, multi-purpose step-down DC/DC controller IC housed in a 5-pin SOT-25 (SOT-23-5 equivalent) surface-mount package. The MPN suffix "C095" denotes a 0.95V fixed reference output variant and "MR" indicates SOT-25 tape-and-reel packaging with a "-G" RoHS-compliant finish. The controller architecture requires only one external P-channel MOSFET, an inductor, a diode, and two capacitors to deliver up to 3A of output current at high efficiency. A step-down DC/DC controller (also called a buck regulator controller) is a switch-mode power supply IC that converts a higher DC input voltage to a lower, regulated DC output voltage by rapidly switching an external power transistor and smoothing the resulting chopped waveform through an LC filter. Buck controllers sit within the broader hierarchy of voltage regulator -> DC-DC converter -> power management IC. Compared with linear regulators, buck controllers achieve much higher efficiency (typically 90%+) because the external switch dissipates far less power than a series pass element. Key features of the XC9220 series include a 1.8V to 16V input voltage range, a 0.9V (±1.5%) precision reference, a 300 kHz internal switching frequency, and built-in soft-start protection. The 'C095' variant configures the feedback divider for a fixed 0.95V output, eliminating external resistors and saving PCB area in single-rail point-of-load designs. The control scheme is fixed-frequency PWM (XC9220 series, as opposed to the XC9221 PWM/PFM family). From a technical perspective, the IC drives an external P-channel MOSFET, allowing the designer to choose a FET rated for the application's load current and thermal envelope. The 300 kHz switching frequency is a deliberate tradeoff between inductor/capacitor size and switching losses, enabling compact designs without pushing into MHz-range EMI sensitivity. Low-ESR ceramic output capacitors are supported, simplifying the BOM versus tantalum-based alternatives. Typical applications include single-cell Li-ion powered portable electronics, USB-powered peripherals, HDD/DVD drive supplies, and 12V-bus distributed power in industrial control boards. The 0.95V fixed output makes it especially well suited as a core-voltage rail for low-voltage DSPs, ASICs, or microcontrollers, where a standard 1.0V LDO cannot meet the dropout budget. When designing with this part, choose the external P-channel MOSFET carefully: its Vds rating must exceed the maximum input voltage plus transient ringing, and its Rds(on) directly sets conduction loss and overall efficiency. Place the Schottky catch diode and input bypass capacitor as close as possible to the SW pin to minimize switching-node parasitic inductance. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes beyond what is available in the manufacturer datasheet, giving engineers a single decision-ready reference for the XC9220C095MR-G.
XC9282B18E0R-G - 600mA HiSAT-COT Sync Step-Down DC/DC | Torex
The Torex Semiconductor XC9282B18E0R-G is a 600 mA synchronous rectification buck (step-down) DC/DC converter using HiSAT-COT control, with a fixed 1.8 V output in a miniature 5-ball WLP-5-06 (0.88 mm x 0.96 mm) wafer-level package. The device operates over a wide input range suitable for single-cell Li-ion battery applications and pairs an internal MOSFET pair for synchronous rectification with a HiSAT-COT (High Speed Advanced Stable - Constant On-Time) control loop that delivers fast transient response with minimal output capacitance. A step-down DC/DC converter (buck regulator) is a switching voltage regulator that converts a higher DC input voltage to a lower DC output voltage at high efficiency by rapidly switching an internal power MOSFET and storing energy in an external inductor. Within the broader taxonomy, this part sits in the hierarchy: synchronous buck converter -> step-down DC/DC converter -> switching voltage regulator -> power management IC -> semiconductor. Its tiny WLBGA footprint and HiSAT-COT topology position it as an ultra-compact, low-profile solution for miniaturized portable equipment where every square millimeter of PCB real estate matters. Key differentiating specifications include the HiSAT-COT control architecture, a continuous 600 mA output current rating, and a 0.88 mm x 0.96 mm 5-XFBGA/WLBGA package that delivers one of the smallest DC/DC land areas in its current class. The synchronous topology eliminates the external Schottky diode, reducing BOM count and improving light-load efficiency versus conventional asynchronous buck designs. The HiSAT-COT control uses a proprietary constant-on-time architecture combined with a high-speed comparator, enabling a high oscillation frequency (compared to legacy COT implementations) that allows the use of a very small external inductor and capacitors. This combination minimizes the external component mounting area while still achieving efficiency equal to or higher than conventional larger parts, making the XC9281/XC9282 series particularly well-suited to space-constrained designs. Typical applications include wearables, hearables, Bluetooth Low Energy modules, IoT sensor nodes, single-cell Li-ion powered handheld instruments, and any miniaturized battery-powered product that demands a stable 1.8 V rail from a Li-ion source. Designers value the part for its small footprint and low BOM cost in USB-powered dongles and disposable medical patches where area is the limiting factor. When designing with the XC9282B18E0R-G, ensure the input capacitor is placed as close as possible to the LX and VIN balls, and follow the recommended inductor value and saturation current rating from the Torex datasheet to maintain stable HiSAT-COT operation across the full load range. Pay particular attention to PCB layout because the WLP-5-06 package requires NSMD pads and trace-width matching on the breakout to the inductor to prevent efficiency loss. This page synthesizes distributor pricing, drop-in alternative recommendations, and practical WLCSP layout notes not consolidated on any single manufacturer or distributor page, giving procurement engineers and PCB designers a single source of cross-validated truth for the XC9282B18E0R-G.

The Infineon XDPE12284C0000XUMA1 is a digital multi-phase PWM controller in the XDP™ family, supporting 8-phase dual-loop operation with output voltages from 0.2 V to 3.04 V. Housed in a compact 40-pin QFN (5x5 mm) package, this controller is engineered for high-current, low-voltage CPU/GPU/ASIC core rails in servers, workstations, and high-end desktop platforms. The part complies with Intel VR13, VR13HC rev 1.3, IMVP8 rev 1.2, and IMVP9 rev 1.3 DC-DC converter specifications, making it a direct fit for Intel-driven core-rail designs. A multi-phase buck controller is a power-management IC that drives several parallel switching phases to deliver high output current with low ripple and excellent thermal distribution. By interleaving the phases, the effective switching frequency seen at the load is multiplied, shrinking the output inductor and capacitor count. The XDPE12284C falls within the broader hierarchy: multi-phase controller → buck controller → DC-DC controller → power management IC → semiconductor device. Key features include SVID rev 1.9.1 protocol compliance for digital communication with the CPU, a PMBus rev 1.3 compliant serial interface for telemetry and programming, dual-loop control for independent rail optimization, and integrated protection such as OVP, OCP, UVP, and OTP. The device supports adaptive voltage positioning and dynamic phase shedding to maximize efficiency across load conditions. The XDPE12284C uses a digital state-machine architecture with an embedded microcontroller for non-volatile configuration and in-circuit telemetry. The 8-phase capability and per-phase current balancing allow it to scale from 60 A server rails up to 600 A HPC accelerator boards. Telemetry through PMBus provides real-time current, voltage, temperature, and fault data for system-level power-capping. Typical applications include VR13/IMVP9 server core rails, AI accelerator POL converters, GPU core power, DDR5 memory VPP rails (with appropriate configuration), and high-end workstation motherboards. Industrial variants extend deployment to telecom equipment and ruggedized computing platforms. When designing with this controller, follow Infineon's reference-design PCB layout guidelines for the 40-QFN exposed pad. The exposed pad must be soldered to a sufficiently large copper pour for thermal and electrical ground. PMBus address selection resistors and SVID bus pull-ups must be placed close to the controller. Use Infineon-validated DrMOS devices (e.g., TDA38826) for best transient performance.

XDPE132G5H-G000 - 16-Phase Digital Buck Controller | Infineon
Infineon Technologies XDPE132G5H-G000 is an industrial digital multiphase PWM controller with 16-phase dual-loop operation, two voltage outputs, and support for high-performance processor power systems using AVSBus, AMD SVI2, or NVIDIA PWMVID. It is packaged as a 56-QFN 7 x 7 mm surface-mount device. A digital multiphase buck controller coordinates multiple power stages to distribute high current across a processor or other demanding digital load. Unlike a single-phase regulator, multiphase control divides regulation work among power stages, supporting higher current capability, improved transient response, and more flexible telemetry. The XDPE132G5H-G000 belongs to the XDP digital power-management controller family and is intended for industrial and high-performance computing systems. The controller can operate in single-loop or dual-loop modes and can be configured for one- or two-phase operation. According to the Infineon datasheet preview, active diode emulation can be enabled automatically or through PMBus, AVSBus, or SVI2 commands. Digitally programmable load-line behavior removes external load-line setting components, while accurate input-current and output-current reporting supports system monitoring and power management. The XDPE132G5H-G000 is designed to work with internal current-sense OptiMOS power stages and provides digital control for demanding rails. Its protocol support lets firmware or platform circuitry communicate operating commands and monitor power-system behavior. The controller's 16-phase architecture is intended to reduce the burden on any one power stage and support high-current rails, while dual-loop regulation can help optimize transient performance. Typical applications include server and desktop processor supplies, accelerator power systems, industrial computing platforms, graphics systems, and other multi-rail equipment using AVSBus, AMD SVI2, or NVIDIA PWMVID. Design work should verify the external power-stage topology, current-sense implementation, gate-drive timing, decoupling, thermal design, and protocol-specific firmware configuration against the manufacturer datasheet. This page combines verified manufacturer and distributor information with practical replacement guidance and design context. Because the provided sources do not include complete electrical tables or verified drop-in equivalents, missing technical values are explicitly marked rather than estimated. The result is intended for engineers evaluating controller architecture, sourcing, and board-level compatibility.
XDPE19283D0000XTMA1 - 8-Phase SVI3 Controller | Infineon
The Infineon XDPE19283D0000XTMA1 is a digital dual-loop 8-phase PWM controller housed in a 40-pin PG-VQFN-13 (5x5 mm) package with exposed thermal pad, designed for AMD SVI3 server, workstation, and high-end desktop CPU power delivery. The device supports configurable phase combinations between two loops (8+0, 7+1, 6+2, 5+3, 4+4), operates across a switching frequency range of 250 kHz to 3000 kHz, and regulates an output voltage window of 0.25 V to 2.8 V with high-precision SVI3 telemetry. Background: A multiphase buck controller is a type of point-of-load (PoL) DC-DC converter controller that interleaves multiple synchronous buck phases to deliver high currents with low ripple, fast transient response, and high efficiency at heavy loads. Multiphase controllers sit within the broader hierarchy of voltage regulator ICs -> DC-DC converters -> power management ICs (PMICs) -> semiconductors, and are commonly used to power advanced CPUs, GPUs, ASICs, and DDR memory rails where single-phase regulators would be impractical due to current demands and thermal constraints. Key features include full AMD SVI3 command and monitor support for dynamic voltage scaling, integrated MOSFET drivers interface, per-loop current balancing, comprehensive fault protection (OVP, UVP, OCP, OTP), and PMBus/I2C telemetry interface. The digital control engine enables adaptive transient response and per-phase current sharing without external compensation components. The dual-loop architecture lets designers dedicate one loop to the CPU Vcore rail and the second loop to a secondary rail (e.g., VDD_MEM or SoC auxiliary). When used with Infineon's OptiMOS power stages, the controller enables very high efficiency across the full load range. Typical applications include AMD EPYC/Ryzen/Threadripper server and workstation CPU core power, high-end desktop motherboards, accelerator card rails (GPU/AI ASIC), and DDR memory termination regulators. For SVI2 legacy platforms or Intel VR13 systems, designers should evaluate the XDPE192C3D or XDPE132G5C families instead, since the SVI3 protocol is required by this controller. The 40-pin VQFN package with exposed pad provides adequate thermal dissipation for the controller IC itself, since most conversion heat is dissipated externally in the power stages.
XDPP1140100BXUMA1 - 32-bit Digital DC-DC Controller, VQFN-24 | Infineon
The Infineon XDPP1140100BXUMA1 is a 32-bit ARM Cortex-M0-based digital power controller optimized for DC-DC converter topologies, including hard-switched full-bridge, half-bridge, push-pull, and active-clamp forward converters. Housed in a 24-pin PG-VQFN-24-20 (4 mm x 4 mm) package, the device integrates firmware-programmable control loops, supports both PWM and LLC modulation schemes, and operates with a switching frequency up to 2 MHz. A digital power supply controller (or digital power converter controller) is a mixed-signal IC that replaces traditional analog PWM controller hardware with a programmable MCU core plus dedicated power peripherals. It belongs to the broader hierarchy of switching regulators -> DC-DC controllers -> power management ICs -> semiconductors. Digital controllers provide adaptive loop compensation, telemetry (VIN/VOUT/IIN/IOUT/TEMP), and PMBus-style configuration that analog controllers cannot match. Key features include an integrated Cortex-M0 core with on-chip nonvolatile memory for firmware, high-resolution DPWM outputs, programmable analog comparators for cycle-by-cycle protection, and integrated gate drivers for synchronous-rectifier FETs. The device supports single-phase topologies and flux balancing for multi-phase designs, while internal ADC channels monitor current, voltage, and temperature with < 1% accuracy. Communication is handled via I2C/UART/PMBus-compatible interfaces. The architecture combines deterministic hardware peripherals with a programmable firmware model, enabling platform reuse across product families. According to the Infineon datasheet, the controller's adaptive dead-time control and body-diode emulation reduce body-diode conduction losses, while per-cycle over-current protection prevents inductor saturation. The 2 MHz switching capability shrinks output filter magnetics, enabling compact, high-density power designs. Typical applications include 48 V telecom isolated bus converters, industrial 24 V input DC-DC bricks, server/crash-cart voltage regulator modules (VRMs), and battery-charging infrastructure. The wide operating range also suits renewable-energy micro-inverters and factory-automation power supplies where telemetry is required. When designing with this part, ensure firmware development follows Infineon's XDP SDK guidelines and that the exposed thermal pad is soldered to a sufficient copper pour. Avoid routing analog signal traces beneath the DPWM outputs to prevent switching-noise coupling into sensitive feedback paths. This page synthesizes Infineon official datasheet content, distributor pricing, and drop-in alternative analysis not found in any single source - giving procurement and design engineers a complete picture in one place.
XDPP1148100BXUMA1 - 100MHz Digital Power Controller | Infineon
The Infineon XDPP1148100BXUMA1 is a digital power supply controller based on a 100 MHz Arm Cortex-M0 core, integrating firmware-programmable control loops for advanced DC-DC and LLC converter topologies. It is offered in a 24-pin PG-VQFN-24-20 package with 4x4 mm footprint and operates from a 2.97V to 3.63V digital supply. The device is designed for high-density AI server, telecom, and 48V bus power applications where firmware-flexible digital control replaces analog PWM controller ICs. A digital power controller is an IC that executes firmware-defined control algorithms - including PID compensation, adaptive dead-time, light-load burst mode, and telemetry - in software rather than analog hardware. Architecturally it sits between the analog power stage (MOSFETs, magnetics, current shunt) and the system management controller, communicating via PMBus, I2C, or UART. The hierarchy is: power management IC -> DC-DC controller -> digital power controller. Compared to analog controllers, digital controllers deliver faster transient response, parametric tuning without hardware changes, and per-unit telemetry that improves system-level observability. Key features include the 100 MHz Cortex-M0 compute core with on-chip non-volatile firmware memory, integrated MOSFET drivers supporting hard-switched and resonant LLC topologies, adaptive dead-time and burst-mode control, and PMBus/I2C control interfaces. The 24-pin VQFN-EP package exposes multiple analog sense inputs (VOUT, ISENSE, temperature) and high-resolution digital PWMs. The XDPP1148100BXUMA1 is typically deployed as the master controller in multi-phase buck, interleaved totem-pole PFC, and full-bridge LLC stages powering 48V-to-PoL conversion in hyperscale data centers. The firmware-defined control law lets one IC cover many topologies and rails without analog IC respins. Design consideration: validate the firmware-programmed current sense gain against the actual DCR/shunt tolerance of the power stage, and respect the VQFN-EP thermal pad layout pattern (a 4x4 array of thermal vias under the EP) to keep junction temperature within the 125C operating limit. This page synthesizes distributor pricing, drop-in alternative analysis, and practical layout notes that are not aggregated in the manufacturer datasheet.
XL4015 - 5A 36V 180kHz Buck Converter | XLSEMI
XLSEMI XL4015 is a 5 A, 36 V fixed-frequency PWM buck step-down DC/DC converter operating at 180 kHz, with low output ripple and line-and-load regulation. The verified manufacturer description identifies internal frequency compensation, a fixed-frequency oscillator, and a requirement for only a minimal number of external components. Those characteristics place the XL4015 in the buck converter hierarchy: DC/DC converter → step-down regulator → switching voltage regulator → power-management semiconductor. The XL4015 is commonly used to reduce a higher DC input to a lower adjustable output. Verified application information identifies 12 V to 3.3 V, 12 V to 5 V, 24 V to 5 V, 24 V to 12 V, and 36 V to 24 V conversions. Its 180 kHz switching frequency supports a compact implementation, while the 5 A load capability makes it more suitable for higher-demand LED, charger, motor-control, and small-heater circuits than low-current regulator modules. The fixed-frequency PWM architecture provides predictable switching behavior and internal compensation, reducing the number of control-loop components required. High efficiency and low ripple are stated advantages, while excellent line and load regulation support stable operation as input voltage or output load changes. The available verified data does not provide exact efficiency curves, ripple limits, feedback voltage, compensation values, or thermal resistance, so those parameters are not inferred here. Typical use includes adjustable DC supplies, lithium-ion and lithium-polymer charging systems, LED lighting, motor control, and small heaters. The adjustable-output architecture allows the same converter family to address several industrial and embedded power rails, provided the input voltage, output current, inductor, diode, capacitors, and thermal conditions remain within the manufacturer’s limits. Designers should treat the XL4015 as a switching regulator rather than a linear regulator: its output filter, compensation network, power loop, and current capability determine transient performance. Place the switching loop and high-current paths compactly, provide the recommended external components from the datasheet, and verify ripple and temperature under the worst-case load. The 5 A rating is a capability statement, not a guarantee that every module or layout can dissipate heat safely. This product page consolidates verified XL4015 specifications, source links, application examples, and the available cross-reference result. It also distinguishes the target IC from generic XL4015 modules, whose board layout, thermal performance, and electrical limits may differ from the manufacturer device.
XL4015E1 - 5A 36V 180kHz Buck DC/DC Converter | XLSEMI
The XLSEMI XL4015E1 is a 180 kHz fixed-frequency PWM buck (step-down) DC/DC converter housed in a TO-263-5 (TO263-5L) surface-mount package with an integrated power MOSFET. It delivers up to 5 A continuous load current from an 8 V to 36 V input rail, producing an adjustable output of 1.25 V to 32 V with up to 96% conversion efficiency, making it a workhorse for cost-sensitive point-of-load applications. A buck (step-down) DC/DC converter is a switch-mode power supply (SMPS) topology that uses a high-side switch, an inductor, and a capacitor to convert a higher DC input voltage into a lower regulated DC output voltage. Unlike a linear regulator, which dissipates excess voltage as heat, a buck converter stores energy in the inductor during the switch ON-time and releases it to the load during the OFF-time, achieving dramatically higher efficiency. Within the broader hierarchy, the XL4015E1 belongs to the family of integrated asynchronous buck regulators that include internal frequency compensation, a fixed-frequency PWM controller, and a power switch on a single die. Key features include a wide 8 V to 36 V input range, internally fixed 180 kHz switching frequency that balances efficiency against external L/C size, low standby current around 5 mA, internal frequency compensation that minimizes external parts, and built-in thermal shutdown and current-limit protection. The TO-263-5L (DPAK-style) package exposes the die tab for low thermal resistance when soldered to a copper pad. The architecture is a classic voltage-mode PWM controller driving an integrated N-channel MOSFET, with feedback sampling from the output via an external resistor divider. Switching at a fixed 180 kHz keeps the fundamental and harmonics away from the AM broadcast band, simplifying EMI filtering in automotive and consumer audio/video products. Efficiency peaks around 90-96% at moderate load and moderate VIN-VOUT delta; efficiency drops at very low or very high duty cycles, which is typical for asynchronous buck converters. Typical applications include 12 V / 24 V lead-acid battery step-down to 5 V or 3.3 V rails for automotive accessories, USB chargers, solar MPPT pre-regulators, LED drivers, and DIY/hobby lab power supplies. The 5-pin footprint is dimensionally similar to LM2596 but with subtly different pin functions, so any second-source design must re-verify the pinout before board layout reuse. When designing with this part, place the input ceramic bypass capacitor and the freewheeling diode as close as possible to the IC, use an inductor with low DC resistance and adequate saturation current (≥ 5 A), and provide at least 1 square inch of copper pad area under the exposed tab to keep the junction within the 125 C limit.
