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.

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.

X5043M8I-2.7A - CPU Supervisor w/ 4K SPI EEPROM | Renesas
The Renesas (formerly Xicor / Intersil) X5043M8I-2.7A is a single-chip CPU supervisor that integrates four critical system functions into one 8-pin MSOP/TSSOP device: power-on reset control, a watchdog timer, supply voltage supervision, and a 4 Kbit block-locked serial EEPROM with an SPI interface. It provides 1 voltage monitor with a factory-trimmed threshold in the 2.7 V family, an active-low reset output in open-drain configuration, and a guaranteed minimum reset timeout of 100 ms. A CPU supervisor (also called a voltage supervisor or reset IC) is a dedicated power-management device that protects a microcontroller, ASIC, or DSP from the brown-out, power-glitch, and firmware-hang conditions that firmware alone cannot detect. Within the broader taxonomy it sits under supervisor and reset IC -> power management IC -> mixed-signal semiconductor. The supervisor's role in a system is to assert a deterministic reset until the supply rail is stable and within tolerance, then continue to monitor VCC and to service a watchdog window that proves the host CPU is still executing valid code. Key features include low VCC operation down to 1 V to support battery-backup EEPROM write, an internal oscillator that removes the need for an external timing component, hardware block-lock protection for the upper half of the EEPROM array via the WP pin, and selectable watchdog timeout options. The SPI serial interface runs at clock rates up to several MHz, suitable for firmware-parameter storage, board-strapping, and calibration tables. The integrated design reduces board area, BOM count, and software overhead compared with discrete supervisor + EEPROM solutions. The architecture combines a precision bandgap reference, a comparator chain for VCC monitoring, a watchdog counter clocked from an internal oscillator, and a high-EEPROM cell array accessed through a standard SPI slave port. The I2C-style three-wire interface uses SCLK, SO, SI, and CS, with the WP input gating writes to the protected memory quadrant. Typical applications include microcontroller reset and parameter storage in industrial controllers, secure boot sequencing in embedded modules, watchdog supervision in motor drives, and EEPROM-backed event logging in metering equipment. Designers choose the X5043M8I-2.7A when a 2.7 V-class reset threshold is required and a small MSOP-8 footprint is mandated. A key design consideration is decoupling: place a 0.1 uF bypass capacitor close to VCC, and observe the CS setup/hold timings for reliable SPI communication at maximum clock rates. The reset pin is open-drain and requires an external pull-up resistor. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the bare manufacturer datasheet.
X5325S8IZ-4.5A - CPU Supervisor with 32K SPI EEPROM, 4.5V | Renesas
The Renesas X5325S8IZ-4.5A is a CPU Supervisor with 32 kBit SPI EEPROM that integrates four essential system-management functions into a single 8-pin SOIC package: power-on reset control, programmable watchdog timer, supply voltage supervision, and block-lock-protected serial EEPROM memory. It is specified for a 4.5 V VCC trip threshold (VCC tolerance +/-10%), operates over the standard industrial temperature range, and offers an active-high reset output (RST) suitable for monitoring 5 V system rails. A CPU Supervisor (also called a voltage supervisor, reset IC, or power-supply monitor) is a mixed-signal IC that safeguards a microcontroller, microprocessor, or DSP by monitoring its supply rail and asserting a reset during brown-out, power-up, and power-down events. This category sits within the PMIC (Power Management IC) hierarchy: supervisor -> PMIC -> power management -> semiconductor. By combining an EEPROM with the supervisor, the X5325 reduces part count, board area, and BOM cost in designs that otherwise need a standalone EEPROM for configuration, calibration, or parameter storage. Key features include a precision VCC voltage detector with 4.5 V nominal trip point, a programmable watchdog timer with selectable time-out, an open-drain / open-collector reset output, SPI (Serial Peripheral Interface) bus access up to 5 MHz for the 32 kbit (4 kbyte) EEPROM, and software-controllable block-lock protection that prevents accidental writes to protected memory regions. The Z suffix indicates the Pb-free (lead-free) finish and the I suffix denotes the industrial temperature grade (-40 C to +85 C). Internally, the X5325S8IZ-4.5a pairs an analog voltage reference and comparator (for VCC monitoring) with a state machine that drives the reset pin and watchdog logic, alongside a separate SPI slave with embedded EEPROM. The 32 kbit EEPROM uses a 4 kbyte organization and supports page-write mode for efficient parameter updates. Block-lock protection prevents rogue firmware from corrupting calibration constants stored in protected sectors, which is critical in safety-relevant designs such as industrial PLCs and appliance controllers. Typical applications include 8051 / ARM Cortex-M0 boot-monitoring in white goods, HVAC controllers, set-top boxes, and any 5 V MCU platform needing tamper-safe parameter storage (e.g., trim settings, serial numbers, runtime hours). The wide VCC tolerance also makes it suitable for 5 V +/-10% industrial 24 V-bus-derived rails. Choose this part when a low-pin-count supervisor plus serial EEPROM in one IC simplifies layout and lowers cost versus a discrete supervisor + standalone EEPROM solution. When designing with this device, place a 0.1 uF decoupling capacitor close to VCC and keep SPI lines short to prevent ringing at 5 MHz. Reset pull-up resistor selection affects rise time - a 10 kohm to 100 kohm range typically balances current draw with rise-time. For in-system EEPROM writes, ensure VCC remains within the data-retention range or block writes with the watchdog-induced reset.

XC6206P302PR-G - 200mA 3V CMOS LDO Regulator | Torex | SOT-89
The Torex XC6206P302PR-G is a 200 mA CMOS low-dropout (LDO) linear regulator with a fixed 3.0 V output, housed in a 3-pin SOT-89 (PR) surface-mount package with a large metal tab for enhanced thermal dissipation. The part accepts an input voltage from 1.8 V to 6.0 V, features a typical dropout of 250 mV at 200 mA load, and consumes only 1 µA quiescent current, making it well-suited for battery-powered portable electronics. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. The LDO belongs to the broader category of linear regulators (which contrasts with switching regulators/DC-DC converters), itself a sub-category of voltage regulators and a key building block in power management ICs. LDOs are favored where low noise, small solution size, and simplicity outweigh the efficiency penalty of burning VIN-VOUT differential as heat. The XC6206 family is positioned at the low-power end of that hierarchy, optimized for cell-powered designs where quiescent current and minimum external parts count dominate the trade-off. Key features include ±2% output voltage accuracy, CMOS process technology, internal short-circuit current limiting, and compatibility with low-ESR ceramic output capacitors - eliminating the bulky tantalum or electrolytic capacitors required by older linear regulators. The SOT-89-3 footprint supports up to ~700 mW dissipation with proper PCB copper area, and the laser-trimmed reference ensures tight output tolerance over the full -40 °C to +85 °C operating range. The XC6206 architecture uses a CMOS pass element and on-chip bandgap-style reference with laser trimming, yielding high ripple rejection and stable operation with only 1 µF ceramic output capacitance. This architecture prioritizes low IQ over very high PSRR, distinguishing it from higher-current LDOs that draw milliamp quiescent current. Typical applications include portable electronics, microcontroller power rails, battery-powered IoT nodes, RFID tags, and wearable sensors. Any single-cell Li-ion or 2x AA system that requires a clean 3 V rail for a MCU or sensor is the sweet spot for this part. When designing, calculate worst-case power dissipation as (VIN - VOUT) × IOUT. With VIN = 4.2 V (full Li-ion), VOUT = 3.0 V, and 200 mA load, dissipation is 240 mW - well within SOT-89 ratings with a small copper pour.

XC6206P332MR - 3.3V 200mA CMOS LDO | Torex | SOT-23
The Torex XC6206P332MR is a fixed 3.3V positive low-dropout (LDO) linear regulator delivering up to 200 mA output current in a 3-pin SOT-23 surface-mount package. It features a 6 V maximum input voltage, a typical 250 mV dropout at rated load, and CMOS construction with on-chip laser-trimmed feedback for high output voltage accuracy. An LDO (low-dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. LDOs belong to the broader class of linear regulators (as opposed to switching regulators), which in turn are categorized under voltage regulators within the power management IC family. Unlike a switching converter that chops the input to achieve high efficiency, a linear LDO simply dissipates the input-to-output voltage difference as heat, trading efficiency for ultra-low output noise and a small, inductor-free footprint. Key differentiating specifications include a 1 µA quiescent current, low-ESR ceramic capacitor compatibility on the output, internal current limiting with fold-back short-circuit protection, and a wide operating temperature range suitable for battery-powered portable and industrial applications. The CMOS process combined with a precision bandgap reference yields tight output tolerance without requiring an external feedback network. Architecturally, the device integrates a power pass transistor, an error amplifier, a bandgap reference, and protective circuitry on a single CMOS die. Because no minimum-ESR output capacitor is required, designers can use small 1 µF ceramic parts and keep the total solution footprint well below 10 mm². Quiescent current in the single-digit microampere range is critical for sleep-mode power budgets. Typical applications include portable battery equipment (single-cell Li-ion to 3.3 V conversion), microcontroller and MCU core supply rails, low-power RF modules, IoT sensor nodes, and USB peripherals where a clean 3.3 V rail must be derived from a 5 V supply. When designing with this part, derate power dissipation by VIN-VOUT times IOUT against the SOT-23 θJA of approximately 250 °C/W; above ~400 mW a copper pour larger than 100 mm² is advisable.
XC6206P332MR-G - 3.3V 200mA LDO Regulator SOT-23 | Torex
The Torex XC6206P332MR-G is a 3.3 V fixed-output, low-dropout (LDO) linear regulator delivering up to 200 mA in a 3-pin SOT-23 surface-mount package. It operates from a 1.8 V to 6.0 V input range, offers a 250 mV typical dropout at 100 mA, and consumes only 1.0 µA quiescent current, making it well suited to battery-powered designs where standby drain must be minimized. An LDO (low-dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is only slightly above the output voltage. LDOs sit within the broader power-management IC hierarchy as a low-noise, simple topology that does not require inductors or switching. Unlike DC-DC converters, an LDO dissipates the difference between input and output as heat, so it is preferred when low noise, small solution size, and fast transient response outweigh concerns about efficiency at high VIN-OUT deltas. Key features of the XC6206P332MR-G include CMOS laser-trimmed output for tight accuracy (typically ±2%), an internal foldback current limiter that doubles as short-circuit protection, and compatibility with low-ESR ceramic output capacitors. The device operates from -40 °C to +85 °C, is rated to 200 mA continuous output, and integrates a thermal shutdown block to protect the die under fault conditions. The chip is housed in a sub-1 mm-thick SOT-23-3 package suitable for hand and reflow soldering. Technically, the regulator uses a P-channel MOSFET pass element with a precision bandgap reference and laser-trimmed feedback divider, allowing output voltages to be programmed in 0.1 V increments between 1.2 V and 5.0 V. Low quiescent current is achieved by biasing internal blocks only as load conditions demand, so the device draws close to 1 µA even with the output under light load. Typical applications include battery-powered IoT sensor nodes, microcontroller core/logic rails, RTC backup supplies, wearable electronics, and post-regulation after a switching converter. The 3.3 V output is a common rail for many MCUs, BLE modules, and low-power wireless ICs. When designing with this part, observe the maximum power dissipation of the SOT-23 package (around 200 mW without copper heatsinking) and ensure VIN does not exceed 6.0 V. Place the input/output ceramic capacitors close to the IC pins to maintain loop stability with low-ESR dielectrics. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that complement the manufacturer datasheet, helping engineers quickly decide whether the XC6206P332MR-G fits their application.
XC6209B292MR - 2.9V 150mA LDO Regulator SOT-25 | Torex
The Torex XC6209B292MR is a high-speed, low-ESR-cap-compatible CMOS LDO regulator that delivers a fixed 2.9 V output at up to 150 mA of load current from a SOT-25 (5-pin) surface-mount package. It belongs to the XC6209B series, a positive-voltage, fixed-output family characterized by 4.17 uVrms-class low noise, sub-200 mV dropout behavior, and an integrated CMOS-on/off control pin (CE). An LDO (low-dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is only marginally above the desired rail. Within the broader power-management hierarchy, LDOs sit beneath switching converters and below traditional NPN/PNP regulators; they trade conversion efficiency for low noise, fast transient response, and a minimal external bill of materials, which is why LDOs are almost always placed downstream of a switching pre-regulator to clean up residual ripple. Key features of the XC6209B292MR include an output voltage accuracy of plus or minus 2 percent, a maximum output current of 150 mA, an ultra-low quiescent current of 25 uA typical, and built-in current-limit plus thermal-shutdown protection. Its CE pin enables shutdown mode that drops the quiescent current to less than 0.1 uA, supporting battery-powered duty-cycled loads. The device accepts input voltages up to 6 V and works with low-ESR ceramic output capacitors as small as 1 uF, simplifying PCB layout. Internally, the XC6209B292MR uses a CMOS pass transistor with a precision bandgap reference and error amplifier. The series is offered in fixed output voltages from 0.9 V to 5.0 V in 0.1 V increments, with the '292' suffix here selecting the 2.9 V nominal rail and 'B' denoting the CE-active-high, low-quiescent variant. Typical applications include cellular-phone and portable-electronics power rails, microcontroller core or I/O supplies, battery charger secondary rails, optical-module bias, and post-regulation after a switching converter. Designers favor the XC6209B292MR where the load demands a quiet, well-regulated 2.9 V source and board area is constrained. When using this regulator, place the input and output ceramic capacitors as close as possible to the VIN and VOUT pins to suppress input-spike transients and to maintain loop stability. Avoid routing high-frequency switching traces near the feedback node to minimize noise injection. This page combines datasheet, distributor pricing, parametric drop-in alternatives, and application design notes so engineers can evaluate and source the XC6209B292MR with confidence.
XC6209B292MR-G - 2.9V 150mA LDO Regulator | Torex SOT-25
The Torex Semiconductor XC6209B292MR-G is a positive-fixed-output CMOS LDO (Low-Dropout) linear regulator delivering 150 mA at a fixed 2.9 V output, housed in a 5-pin SOT-25 surface-mount package. It accepts input voltages up to 10 V, features a typical quiescent current of 25 µA, and operates over the -40 to +85 °C industrial temperature range, making it well-suited for compact battery-powered designs. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. LDOs sit within the broader hierarchy of linear regulators → voltage regulators → power management ICs → semiconductors, and they are preferred over switching regulators in noise-sensitive applications because they introduce no high-frequency ripple to the output rail. Key specifications include an input voltage range up to 10 V, fixed 2.9 V output, 150 mA continuous output current, 25 µA quiescent current, low-ESR ceramic-capacitor compatibility, and built-in current-limit / short-circuit protection. The foldback current limiter also acts as an output short-circuit protector, ensuring robust behavior during fault conditions. The XC6209B292MR-G employs a CMOS architecture with an internal reference and pass transistor, and is designed for high-speed transient response so output fluctuations remain small during sudden load steps. The series maintains stable regulation even with low-ESR ceramic output capacitors, eliminating the bulky tantalum capacitors required by older LDO designs. Typical applications include battery-powered portable equipment, microcontroller and MCU core supply rails, IoT sensor nodes, wearable electronics, and as a post-regulator following a switching converter in mixed-rail systems. The low quiescent current extends battery life in always-on applications such as wireless sensor nodes and BLE peripherals. When designing with this device, ensure input and output ceramic capacitors are placed as close to the IC pins as possible (typically 1 µF to 4.7 µF X7R/X5R), and verify that VIN remains at least above the dropout headroom of the regulated 2.9 V output under worst-case load to maintain regulation. Avoid reverse-biasing VIN below VOUT which can back-feed the output node. This page synthesizes distributor pricing, drop-in alternatives from the same Torex XC6209 family, and practical design notes not found in the manufacturer datasheet. Engineers can compare same-voltage and near-voltage siblings in the same SOT-25 footprint, enabling PCB layout reuse across product variants.
XC6505B501MR-G - 200mA LDO Regulator, 5V Fixed, 10.5V Max Input | Torex
The Torex Semiconductor XC6505B501MR-G is a low quiescent current, high-speed 200 mA LDO (Low-Dropout) linear regulator with a fixed 5.0 V output, packaged in a 5-pin SOT-25 surface-mount package. It accepts inputs from 1.7 V to 10.5 V and delivers up to 200 mA of continuous output current at a typical dropout of 140 mV. The XAIPART answer capsule: brand + MPN, product type (LDO linear regulator), three headline specs (5 V fixed output, 200 mA IOUT, 10.5 V max VIN), package (SOT-25). Background context: an LDO (Low-Dropout) regulator is a subclass of linear voltage regulator that maintains a stable output voltage even when the difference between input and output voltage is small (low dropout). Within the broader hierarchy, the XC6505B501MR-G sits under: LDO -> linear regulator -> voltage regulator -> power management IC (PMIC) -> semiconductor. Its role in a system is to provide a clean, low-ripple supply rail to downstream analog or digital loads from a higher-voltage or noisy input rail. Key features include a low quiescent current (Torex markets the family as 'Low Quiescent Current'), high-speed transient response, integrated overcurrent protection, and a typical dropout of only 140 mV at 200 mA load. The fixed 5.0 V output eliminates external resistor dividers, simplifying BOM and saving PCB real estate compared with adjustable-output LDOs. The SOT-25 (5-pin SOT-23 family) package is one of the most common small-footprint surface-mount packages, enabling compact designs in space-constrained applications. Architecturally, the XC6505B501 uses a P-channel MOSFET pass element topology, which is why dropout is held to 140 mV and quiescent current remains low. The high-speed error amplifier and small output capacitor requirement allow the regulator to respond quickly to load transients, making it suitable for digital logic and RF supply rails where fast dynamic load steps occur. Typical applications include battery-powered portable electronics, IoT sensor modules, microcontroller (MCU) and digital logic power rails, and as a post-regulator following a switching converter to suppress switching ripple. The 5.0 V fixed output is a direct match for many MCU and sensor supply requirements. For broader system use, the XC6505 series from Torex is also offered in other fixed voltages (e.g., 3.3 V) within the same SOT-25 footprint, enabling PCB layout reuse. Design tip: ensure the input capacitor meets the datasheet ESR/ceramic-X7R requirements, and place it close to the VIN pin to suppress input-voltage ringing during load transients. Verify that maximum power dissipation does not exceed the SOT-25 thermal rating at your ambient temperature - at 200 mA and a high VIN-VOUT differential, the regulator can dissipate several hundred milliwatts. This page synthesizes distributor pricing, drop-in cross-references, application circuits, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single reference to evaluate, source, and design with the XC6505B501MR-G.
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.

Typical applications include VR13/VR13HC server core rails, IMVP8/IMVP9 workstation VCCIN, high-end desktop CPU cores, AI accelerator cards, and HPC accelerator boards. The 8-phase capability scales to deliver tens-to-hundreds of amps when paired with Infineon DrMOS power stages such as the TDA21472 or OptiMOS power stages. When designing with this controller, pay close attention to PCB layout symmetry between phase nodes, use low-ESL ceramic input capacitors near each phase, and follow Infineon's reference design for current-sense resistor placement. Telemetry configuration via PMBus must be validated against platform firmware before mass production.

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.
