An isolated DC-DC converter is a switched-mode power module that uses a high-frequency transformer to provide galvanic isolation between input and output while stepping a high-voltage DC bus down to a lower voltage rail. Within the power-conversion hierarchy, isolated converters sit alongside non-isolated POL regulators and AC-DC front ends, and they are typically deployed after PFC and bulk-capacitor stages in distributed-power architectures. The V375A36T400BL belongs to Vicor's Maxi family, which is known for high efficiency, low noise, and rugged operation in industrial, military, and aerospace power systems. Key specifications include an output current of 11.1A (400W total), an input range of 250V to 425V DC (375V nominal), an input-surge withstand of 500V for 100ms, output regulation of ±0.35% no-load to full-load, and high-speed MOSFET switching topology. The module also features an isolated output, programmable output trim, and a typical conversion efficiency in the mid-80% to low-90% range depending on operating point. The through-hole package provides robust mechanical mounting for chassis and PCB backplane designs in harsh environments. The V375A36T400BL uses Vicor's proprietary Sine Amplitude Converter (SAC) topology or a similar high-frequency resonant topology to achieve soft switching and high power density. This topology minimizes switching losses and reduces EMI relative to hard-switched PWM converters, making the module suitable for noise-sensitive analog and RF subsystems sharing the same chassis. Typical applications include industrial 380V rectified-bus distribution, railway rolling-stock auxiliary power, high-voltage battery energy storage, military C4ISR platforms, and telecom -48V/-60V central-office equipment. The wide 250-425V input range makes the module well suited to nominal 300V, 330V, or 400V intermediate bus voltages generated from three-phase PFC front ends. When integrating this module, ensure the upstream bulk capacitance meets the input-ripple and inrush requirements specified in the datasheet, and verify that the host PCB thermal design keeps the module baseplate below its maximum operating temperature.

The Maxi family sits within Vicor's brick-converter hierarchy (Junior, Mini, Maxi, Micro) and is targeted at 200-400 W+ output levels where PCB-area-per-watt efficiency and thermal performance matter more than a discrete switching regulator. The isolation barrier also breaks ground loops and lets the output reference shift freely relative to the input bus. Key specifications include ±0.25 % line/load regulation from no load to full load, a wide operating temperature range of -20 °C to +100 °C, and high efficiency typical of Vicor's zero-current-switching (ZCS) topology. The module integrates filtering, soft-start, and overtemperature protection, and its output trim pin (TRIM) lets designers adjust Vout between 4.8 V and 52.8 V without changing the transformer ratio. Technically, the V375A48C600BF uses a fixed-ratio, high-frequency ZCS forward converter topology that switches at a fixed frequency and uses the inherent resonance of the transformer magnetics to switch at zero current, dramatically reducing switching losses and EMI. This topology enables the wide input range while keeping the magnetics small and the converter efficiency high, which directly shrinks the heatsink requirements. Typical applications include 380 V industrial bus DC-DC conversion, railway traction auxiliary supplies, high-voltage battery systems in electric vehicles, industrial motor drives, semiconductor test equipment, and military/aerospace power systems where 28 V or 48 V rails are derived from a high-voltage DC bus.

Typical applications for the VTM1408S52Z0250T00 include powering high-current processors, ASICs, and FPGAs in advanced computing platforms, data-center CPU cores, AI accelerator cards, GPU core rails, telecom base-station digital cards, and high-density server voltage regulator modules. It is typically used downstream of a Vicor PRM that provides the regulated sine-amplitude input. When designing with this VTM, plan the upstream PRM stage to deliver a clean, regulated DC input matched to the VTM K-factor, and place input bypass capacitance close to the SAC input pads to take advantage of the relocated bulk-capacitance topology. Confirm that the VTM output is followed by a fast point-of-load regulator for sub-1V rails and that thermal copper area meets the chiP package dissipation requirements.

VTM2308S52Z0276T00 - 103.3A Non-Iso PoL Module | Vicor
The Vicor Corporation VTM2308S52Z0276T00 is a non-isolated Point-of-Load (PoL) Current Multiplier module delivering up to 103.33 A output current at 1.2 V from a 38.4 V input, housed in a surface-mount ChiP package. It is a member of Vicor's VTM (Voltage Transformation Module) family within the Factorized Power Architecture (FPA), designed to perform the final voltage transformation close to the load with extremely low noise and high bandwidth. A Voltage Transformation Module (VTM) is a sine amplitude converter (SAC)-based DC-DC building block that delivers isolated-ratio voltage transformation and current multiplication without intermediate energy storage. Within Vicor's FPA hierarchy, a VTM sits downstream of a PRM (Pre-Regulation Module) that establishes a stable intermediate bus; the VTM then performs fast, low-noise point-of-load conversion. In the broader taxonomy, a VTM belongs to non-isolated DC-DC converters, which fall under board-mount power supplies, a sub-category of power management ICs and modules. Key specifications include a 1.2 V fixed output, 103.33 A maximum output current, and a 38.4 V maximum input voltage (typically powered from a 36-38 V PRM-rail). The device achieves up to 96% efficiency and supports a typical power density above 1,000 W/in³, enabling very compact high-current PoL rails for advanced processors, ASICs, and AI accelerators. Its ChiP surface-mount package enables top-side or bottom-side PCB mounting and efficient heat extraction via the package's integrated thermal interface. The VTM2308S52Z0276T00 uses Vicor's zero-current-switching SAC topology, eliminating high-frequency switching edges on the output and minimizing EMI. This topology delivers a flat efficiency curve, fast transient response, and accurate line/load regulation without the need for output inductors. The result is a clean, low-noise 1.2 V rail suitable for direct parallel connection to low-voltage, high-current digital loads that are intolerant of switching noise and ripple. Typical applications include AI/GPU core voltage rails, high-performance ASIC PoL conversion, datacenter processor power delivery, telecom base-station digital ASIC supplies, and high-density computing boards where board area and thermal budget are constrained. The 1.2 V output is a common rail voltage for advanced processors, FPGAs, and high-speed memory interfaces. When designing with this device, the upstream PRM must be selected to provide a regulated 36-38 V input bus; the VTM alone is not a stand-alone regulator. PCB layout should minimize the loop area between the VTM output pads and the load, use a copper heat-spreader or thermal via array beneath the ChiP, and follow Vicor's recommended land pattern from the datasheet to preserve electrical and thermal performance.

VTM2308S52Z0276T01 - 103.33A Non-Isolated PoL Module | Vicor
The Vicor VTM2308S52Z0276T01 is a non-isolated Point-of-Load (PoL) current multiplier module that delivers 1.2V at up to 103.33A from a 38.4V nominal input, packaged in the Vicor 2308 SM-CHIP (ChiP) surface-mount platform. It belongs to the VTM (Voltage Transformation Module) family of Sine Amplitude Converter (SAC) topology products that provide a high-ratio, fixed voltage transformation close to the load. A Voltage Transformation Module (VTM) is a non-isolated, fixed-ratio DC-DC converter used as a building block inside a Factorized Power Architecture (FPA). Within FPA the upstream PRM (Pre-Regulation Module) provides the regulated input, while the downstream VTM performs fast, low-impedance current multiplication and voltage transformation. As a current multiplier, the VTM2308 belongs to the wider hierarchy: DC-DC converter -> non-isolated PoL module -> current multiplier -> power management IC. The SAC topology uses zero-voltage and zero-current switching to achieve high efficiency and very fast transient response at megahertz effective bandwidth. Key features include a 38.4V nominal input voltage, a fixed 1.2V output, a continuous output current of 103.33A, and the very small 2308 ChiP package outline. Because the VTM is purely a voltage transformation stage, the input voltage must already be preregulated upstream; the module does not regulate output voltage by itself. This makes the VTM ideal for high-current, low-voltage CPU/GPU/ASIC core rails where regulation is handled by a closed-loop PRM+VTM or PRM+VTM+loop combination. Typical applications include high-performance computing core voltage rails, AI accelerator and GPU POL conversion, datacom and telecom 48V-to-1V direct conversion, FPGA and ASIC auxiliary rails, and high-density server power distribution where the VTM is placed immediately adjacent to the load. The fixed 1.2V output is convenient for legacy 1.2V logic rails and many DDR3/DDR4 secondary rails. When designing with the VTM2308S52Z0276T01, ensure the upstream PRM provides a regulated, low-noise input within the supported window, and follow Vicor's ChiP layout guidelines for thermal vias, copper area, and input/output bypassing. Because there is no internal over-current or over-voltage regulation, system-level fusing and PRM-side protection are required.
VTM2308S60Z01A1T00 - 131A 48V VTM Current Multiplier | Vicor
The Vicor VTM2308S60Z01A1T00 is a non-isolated Point-of-Load (PoL) current multiplier module delivering up to 131 A output at 1 V from a 48 V nominal input bus, housed in a 2308 SM-CHIP surface-mount package. It is a member of Vicor's VTM (Voltage Transformation Module) Current Multiplier family, designed to sit downstream of a VI BRICK or factorized power front-end to provide high-current, low-voltage rails directly at the load. A Voltage Transformation Module (VTM) is a specialized non-isolated DC-DC converter topology developed by Vicor that uses a proprietary zero-current-switching (ZCS) / zero-voltage-switching (ZVS) sine-amplitude-converter (SAC) architecture. The VTM family belongs to the broader hierarchical group of factorized power architecture (FPA) components, which in turn are a sub-category of board-mount DC-DC converters and ultimately power management ICs/modules. VTMs deliver a fixed transformation ratio (K-factor), are bidirectional, and exhibit very low output impedance - effectively multiplying output current while dividing voltage. Key specifications include a 1 V output voltage, 131 A continuous output current, 48 V nominal input, and the high-efficiency SAC switching topology that minimizes switching losses. The 2308 SM-CHIP package integrates the SAC transformer and switching elements into a single surface-mount module, eliminating external magnetics and reducing total solution size compared with discrete synchronous buck designs. Operating temperature range and full-load efficiency numbers are published in the manufacturer datasheet. Architecturally, the VTM2308S60Z01A1T00 uses Vicor's proprietary sine-amplitude-converter topology, which provides bidirectional current flow, fixed K-factor voltage transformation, and very fast transient response due to its low output impedance. Combined with a VI CHIP PRM pre-regulator upstream, it forms a complete factorized power solution that outperforms conventional intermediate-bus converters for high-current CPU/GPU core or POL applications. Typical applications include 48 V direct-to-POL conversion for high-current processors (CPUs, GPUs, ASICs), high-performance computing and AI accelerator boards, telecom equipment 48 V backplane distribution, and server motherboard core voltage rails where board real estate and efficiency are critical. When designing with this VTM, ensure that the upstream PRM or supply can source the reflected input current (Iin = Iout × K-factor), provide adequate thermal management under the 2308 SM-CHIP package, and respect the input voltage and polarity ratings. The module is non-isolated, so input-to-output isolation must be provided elsewhere in the system (typically in the upstream PRM/BCM). This page synthesizes real distributor pricing, drop-in alternative candidates from web cross-reference data, and practical design notes not found in the bare manufacturer datasheet - useful for engineers evaluating the VTM2308S60Z01A1T00 for new high-current POL designs.
VTM2308S60Z0825T00 - 25A VTM Current Multiplier 48V | Vicor
The Vicor VTM2308S60Z0825T00 is a VTM (Voltage Transformation Module) current multiplier module that delivers up to 25A of output current at 7.5V from a 26-60V input bus, packaged in Vicor's surface-mount SM-ChiP (co-molded ChiP) form factor. It is rated for 188W output power and operates as a fixed-ratio DC-DC transformer with a K factor of 1/4 (48V to 7.5V step-down). The proprietary Sine Amplitude Converter (SAC) topology with zero-current-switching (ZCS) and zero-voltage-switching (ZVS) is engineered for multi-megahertz switching frequencies, enabling extremely high power density. A VTM is a class of isolated/non-isolated Point-of-Load (PoL) DC-DC transformer module used inside Vicor's Factorized Power Architecture (FPA). Positioned downstream of a PRM (Pre-Regulator Module), the VTM performs the second-stage current multiplication, transforming a regulated intermediate bus into a low-voltage, high-current PoL output for processors, ASICs, and FPGAs. The taxonomy: VTM current multiplier -> DC-DC transformer -> Point-of-Load module -> board-mount power module -> power management. Key features include 96%+ typical efficiency at full load, a wide input operating range of 26V to 60V (48V nominal compliant), tightly regulated output across the load range, and a co-molded ChiP package with superior thermal conductivity. The SM-ChiP package is compatible with standard pick-and-place assembly processes used in high-volume manufacturing lines, eliminating the need for through-hole or socketed mounting. The device operates as a fixed-ratio transformer - it provides isolation (in K=1/4 versions) when paired with appropriate upstream regulation and produces an output that is a fixed fraction of its input. The ZCS/ZVS SAC topology achieves MHz-class switching without the typical switching losses, giving the module a high power density of approximately 1000 W/in^3. Typical applications include 48V direct-to-PoL power for high-performance processors, GPUs, AI accelerators, ASICs, and downstream DC-DC conversion in data-center, telecom, and industrial automation systems where the Factorized Power Architecture is used. The high efficiency and density suit both compute and rugged-environment boards. When designing with this part, always pair it with a compatible PRM upstream regulator (such as Vicor PRM48 series) to establish the regulated intermediate bus. External input/output bulk capacitors and decoupling must follow the Vicor reference PCB layout - parasitic inductance on the high-current pads materially impacts efficiency and ripple. The M-Drive compatible interface supports telemetry, fault reporting, and adaptive loop control when paired with a Vicor Digital Supervisor.
VTM2308S60Z0825T00 - 25A VTM Current Multiplier 7.5V Out | Vicor
The Vicor VTM2308S60Z0825T00 is a member of the VTM™ (Voltage Transformation Module) family of fixed-ratio, non-isolated DC-DC current multiplier modules, delivering 7.5V nominal output at up to 25 A from a 26V to 60V input bus. Housed in a surface-mount SM-ChiP™ co-molded package with enhanced thermal interface area, the VTM2308 operates as a point-of-load (PoL) current multiplier paired upstream with a Vicor PRM (Pre-Regulation Module) to deliver a regulated, fast-transient low-voltage rail. The proprietary multi-megahertz ZCS/ZVS Sine Amplitude Converter™ (SAC™) topology achieves very high conversion efficiency and very low output impedance, making this module ideal for high-current, low-voltage processor and ASIC loads. What is a VTM (Voltage Transformation Module)? A VTM is a fixed-ratio isolated or non-isolated DC-DC transformer module - also referred to as a Point-of-Load current multiplier - that operates from a regulated primary bus to deliver isolated or non-isolated outputs at high current. Conceptually it sits within the factorized power architecture between a PRM (which provides the regulated input) and the load, performing the high-current voltage step-down at extremely high bandwidth. Its hierarchical placement is: DC-DC transformer / current multiplier → DC-DC converter module → power module → power management IC → semiconductor. Key electrical specifications include a 26V to 60V input operating range, nominal 7.5V output at 25 A (188 W output power), and a K-factor of 1/8 (8:1 step-down). The device is specified over -40 °C to +125 °C internal temperature (T-Grade). The SM-ChiP surface-mount form factor is compatible with standard pick-and-place assembly processes. Co-molded ChiP packaging provides enhanced thermal management via a large thermal interface area and superior thermal conductivity, allowing the high-efficiency VTM2308 to deliver its 188W output without external heatsinks on properly laid-out 4+ layer PCBs. The VTM2308 leverages Vicor's SAC™ zero-current-switching / zero-voltage-switching topology to minimize switching losses and EMI. Compared with conventional buck or forward-converter approaches at the same power level, the VTM achieves higher efficiency, faster transient response, and substantially lower stored energy per cycle, allowing tighter output voltage regulation under dynamic loads and enabling downstream capacitance to be dramatically reduced. Typical applications include high-current point-of-load regulation for processors, ASICs, FPGAs, and GPUs; telecom and datacom 48 V bus architectures; factory-automation and test-equipment power rails; and any system where a Vicor PRM front-end regulates an intermediate bus and the VTM2308 performs the final low-voltage, high-current step to the load with very high bandwidth. When designing with this device, coordinate upstream with a compatible Vicor PRM module such as the PRM2311 or PRM2341 family: the VTM is a fixed-ratio current multiplier and does not regulate on its own. Provide adequate PCB copper area beneath the SM-ChiP thermal interface and follow Vicor's layout guide for input/output loop inductance minimization to preserve the SAC™ topology's efficiency and noise margins.

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.
