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.

The controller is engineered to deliver high-core-count CPU and GPU power rails with sub-millisecond transient response. The device implements a digital control loop architecture, replacing traditional analog compensation with firmware-driven state machines and ADC-based feedback. This allows Infineon's GUI and PMBus commands to tune loop compensation, fault thresholds, and telemetry without external component changes, while maintaining tight regulation across wide load steps typical of compute workloads. 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. This page synthesizes distributor pricing, package-level drop-in alternatives, and practical design notes that go beyond what is printed in the manufacturer datasheet, giving procurement and design engineers a single source for sourcing and replacement decisions.

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.

It is housed in a 40-pin QFN package rated for industrial environments. A digital multiphase controller is a power-management IC that orchestrates multiple parallel buck converter phases to deliver high currents at low voltages with fast transient response. Within the broader hierarchy, the XDPE19283B sits as a multiphase controller -> DC-DC controller -> power management IC -> semiconductor. Such devices replace single-phase voltage regulators in CPU/GPU core rails where the load can swing from a few amps to over 100 A in microseconds, and where telemetry, fault handling, and adaptive voltage positioning are mandatory. Key features include AMD SVI3 Rev 2.0 compliance, PMBus rev 1.3 serial interface support up to 1 MHz, flexible PWM phase ordering and phase shedding, and per-loop digital compensation. The integrated ARM Cortex-M0 core handles telemetry, fault logging, and configuration via PMBus, while the analog front end provides accurate current sensing and adaptive transient response. Loop multiplexing enables asymmetric rail configurations such as 6+2 for core + integrated graphics on AMD HEDT platforms. Architecture-wise, the device combines two independent digital control loops that each manage a programmable number of phases. Per-phase current sharing and temperature balancing are handled in firmware, which lets the same silicon serve multiple platform form factors. The PMBus interface exposes telemetry for VIN, VOUT, IOUT, temperature, and fault status, and supports both AVS and dynamic load-line trim. Typical applications include AMD SP3/SP5 socket core voltage rails, HEDT processor platforms, server memory termination, and high-current ASIC rails. Pair the controller with Infineon OptiMOS power stages such as TDA21462AUMA1 or TDA21525, plus an external divider and a PMBus-capable supervisor. The device is targeted at high-volume server OEMs, so expect long-term production support from Infineon. Ensure your PCB provides adequate copper and thermal vias beneath the exposed pad to keep junction temperature within limits under full phase count.
XDPE19283B0000XUMA1 - 8-Phase Dual-Loop Digital Controller | Infineon
The Infineon XDPE19283B0000XUMA1 is a digital dual-loop 8-phase PWM controller designed for AMD SVI3 Rev 2.0 compliant CPU/GPU core voltage regulation, packaged in a 40-pin VQFN (PG-VQFN-40-13). It supports an output voltage range of 0.25 V to 2.8 V with 5 mV step resolution and configurable phase combinations including 8+0, 7+1, 6+2, and 4+4 for flexible load-line balancing. A multiphase buck controller is a power-management IC that drives multiple synchronous buck phases in parallel to supply high-current CPU/GPU/SoC core rails. Within the broader power-management IC hierarchy, a digital multiphase controller sits above simple voltage regulators and below fully integrated PMICs; it pairs an analog front end with a programmable digital core (in this case, an ARM Cortex-M0) for telemetry, fault handling, and adaptive loop compensation. Key features include a programmable ARM Cortex-M0 processor for non-volatile configuration, PMBus rev 1.3 compliant serial interface supporting up to 1 MHz bus speed, and per-phase current sensing for accurate load-line regulation. The controller integrates high-performance analog front ends with digital control loops, supports flexible PWM phase order and phase shedding, and provides extensive telemetry for voltage, current, and temperature. The XDPE19283B employs an analog front-end plus digital control-loop architecture, where the ARM Cortex-M0 manages telemetry, fault response, and adaptive voltage positioning. Compared with purely analog multiphase controllers, the digital core enables firmware-updatable configurations, per-rail loop tuning, and full PMBus monitoring - critical for AMD SVI3 platforms that require precise dynamic VID transitions. Typical applications include AMD AM5/TR5 desktop and server CPU VR cores, workstation motherboard Vcore rails, GPU accelerator cards with SVI3 interfaces, and high-end desktop VRM modules. The 8-phase capability delivers the high continuous currents demanded by modern multi-core CPUs under transient load. When designing with this part, follow the Infineon reference layout for the PG-VQFN-40-13 exposed-pad package and observe AMD SVI3 platform bring-up sequencing. The PMBus address and rail configuration are set by external strapping resistors. This page synthesizes distributor pricing, Infineon same-family alternatives, and practical design guidance that the manufacturer datasheet alone does not present, helping procurement and engineering teams evaluate the XDPE19283B0000XUMA1 for new designs and second-source validation.
XDPE19283D0000XTMA1 - 8-Phase SVI3 Controller | Infineon
The Infineon XDPE19283D0000XTMA1 is a digital dual-loop 8-phase PWM controller housed in a 40-pin PG-VQFN-13 (5x5 mm) package with exposed thermal pad, designed for AMD SVI3 server, workstation, and high-end desktop CPU power delivery. The device supports configurable phase combinations between two loops (8+0, 7+1, 6+2, 5+3, 4+4), operates across a switching frequency range of 250 kHz to 3000 kHz, and regulates an output voltage window of 0.25 V to 2.8 V with high-precision SVI3 telemetry. Background: A multiphase buck controller is a type of point-of-load (PoL) DC-DC converter controller that interleaves multiple synchronous buck phases to deliver high currents with low ripple, fast transient response, and high efficiency at heavy loads. Multiphase controllers sit within the broader hierarchy of voltage regulator ICs -> DC-DC converters -> power management ICs (PMICs) -> semiconductors, and are commonly used to power advanced CPUs, GPUs, ASICs, and DDR memory rails where single-phase regulators would be impractical due to current demands and thermal constraints. Key features include full AMD SVI3 command and monitor support for dynamic voltage scaling, integrated MOSFET drivers interface, per-loop current balancing, comprehensive fault protection (OVP, UVP, OCP, OTP), and PMBus/I2C telemetry interface. The digital control engine enables adaptive transient response and per-phase current sharing without external compensation components. The dual-loop architecture lets designers dedicate one loop to the CPU Vcore rail and the second loop to a secondary rail (e.g., VDD_MEM or SoC auxiliary). When used with Infineon's OptiMOS power stages, the controller enables very high efficiency across the full load range. Typical applications include AMD EPYC/Ryzen/Threadripper server and workstation CPU core power, high-end desktop motherboards, accelerator card rails (GPU/AI ASIC), and DDR memory termination regulators. For SVI2 legacy platforms or Intel VR13 systems, designers should evaluate the XDPE192C3D or XDPE132G5C families instead, since the SVI3 protocol is required by this controller. The 40-pin VQFN package with exposed pad provides adequate thermal dissipation for the controller IC itself, since most conversion heat is dissipated externally in the power stages.
XDPE192C4C0000XTMA1 - 12-Phase Digital VR14 Controller | Infineon
The Infineon XDPE192C4C0000XTMA1 is a digital dual-loop 12-phase PWM controller in a 40-pin 5x5 mm QFN package (PG-VQFN-48-63), designed for Intel VR13, VR13HC, and VR14 server, workstation, and high-end desktop CPU/Core voltage regulation. It integrates a high-performance analog front end with an ARM Cortex-M0 processor and supports PMBus revision 1.3.1 with up to 1 MHz bus speed, plus Intel SVID Rev 1.94 and IMVP9.1/9.2 compliance for direct attach to Intel VR14 server platforms. A digital multiphase controller is a power-supply IC that orchestrates multiple parallel buck converter phases to deliver high output current at low voltage, dynamically shedding phases to optimize efficiency at light load. The XDPE192C4 belongs to the broader family of multiphase buck controllers in the power management IC hierarchy, sitting between a discrete buck converter and a fully integrated VR module. Key features include flexible dual-loop control with up to 12 phases allocated between the Core rail and a second loop for the I/O or memory rail, digitally programmable PID loop compensation, Active Transient Response (ATR/FATR), automatic phase shedding, fast DVID response, and Pulse Frequency Modulation (PFM) for light-load efficiency. The digital architecture enables per-platform firmware configuration rather than external resistor-set loop components. The architecture combines a high-resolution analog current-sense front end, an ARM Cortex-M0 digital control core, and PMBus telemetry, supporting telemetry for voltage, current, temperature, and fault status. The 5x5 mm PG-VQFN-48-63 package uses an exposed pad for thermal relief, suitable for forced-air server environments. Typical applications include VR14 server motherboards, workstation and high-end desktop CPU VRs, memory VRTT rails, and embedded compute platforms. Pairing the controller with Infineon OptiMOS power stages such as TDA38826 builds a complete digital multiphase VR solution. When designing with the XDPE192C4, ensure the PMBus address strap and boot configuration resistors are set per platform firmware. The exposed pad must be soldered to a sufficiently large copper area (at least 1 sq. inch) for the thermal envelope during 12-phase full-load operation. The PMBus pull-ups should be sized for the selected bus speed (100 kHz to 1 MHz). This page synthesizes Infineon datasheet parameters, distributor pricing, and validated drop-in alternatives not found in the manufacturer datasheet alone, providing a complete engineering reference for the XDPE192C4C0000XTMA1.
XDPE1A2G5B0000XUMA1 - 16-Phase Digital Multiphase Controller | Infineon
Infineon Technologies XDPE1A2G5B0000XUMA1 is a 16-phase digital dual-loop multiphase controller housed in a 56-pin PG-VQFN exposed-pad package, designed for high-performance processor voltage regulation. The part delivers an output range of 0.05V to 3.1V, supports up to 16 phases across two independent loops, and accepts multi-vendor pin-compatible integrated power stages with trivalent PWM interfaces for maximum power-stage flexibility. It is specified for industrial operating conditions and is part of Infineon's XDPE digital multiphase controller family. What is a digital multiphase controller? A digital multiphase controller is a semiconductor device that orchestrates multiple parallel power stages (phases) to convert a higher input voltage to a tightly regulated lower output voltage for processors, ASICs, and memory. It sits in the hierarchy: multiphase controller -> DC-DC converter -> power management IC -> semiconductor. Digital controllers use firmware-configurable control loops, PMBus/SMBus telemetry, and adaptive voltage positioning to deliver faster transient response than analog controllers, while remaining programmable per rail. Key features of the XDPE1A2G5B include up to 16 phases (dual loop, configurable as 8+8, 12+4, 16+0, etc.), per-loop digital control with adaptive transient response, integrated current and temperature sensing through the trivalent PWM interface, advanced fault detection (OVP, UVP, OCP, OTP), and PMBus 1.3.1 compliant telemetry for VOUT, IOUT, temperature, and status. The 56-pin PG-VQFN package includes an exposed thermal pad (EP) that must be soldered to a top-layer copper pour for heatsinking. Architecturally, the device uses a 32-bit control core with on-chip non-volatile memory for configuration, dual high-resolution DPWM engines, and a per-phase current-share loop. Multi-vendor compatibility is achieved through the standard trivalent PWM protocol, allowing pairing with Infineon's OptiMOS power stages as well as third-party compliant stages. This design reduces BOM count by integrating temperature and current sense directly from the power stage, eliminating external sense elements. Typical applications include high-current server and data-center processor rails (Intel/AMD VR13, VR14 compliant rails), telecom and networking ASIC power, DDR5 memory termination and VTT rails, GPU and AI accelerator core power, and high-end workstation voltage regulation. The dual-loop architecture also enables use cases such as powering a CPU core rail plus a separate memory/IO rail from a single controller. When designing with the XDPE1A2G5B, follow Infineon's reference layout guidelines: a 4-layer PCB minimum with a dedicated ground plane, the exposed pad soldered to a 1 oz copper pour of at least 200 mm², and input capacitors placed within 5 mm of the power-stage inputs. Configuration firmware must be loaded via the Infineon configuration tool or compatible PMBus programmer before the rail becomes active; the device does not boot into a default operating mode without valid configuration.

XDPL8105XUMA1 - Digital Flyback LED Driver IC | Infineon
The Infineon XDPL8105XUMA1 is a digital single-stage flyback controller IC with high power factor and primary-side regulation designed for cost-effective constant-current LED drivers. It operates from 100-277 VAC input with >90% efficiency, supports a switching frequency range of 3 kHz to 180 kHz, and is housed in an 8-pin PG-DSO-8 (SOIC-8) surface-mount package. The XDP digital platform combines primary-side regulation with active PFC, eliminating the need for an optocoupler and secondary-side feedback components. A flyback controller is a switch-mode power supply (SMPS) topology regulator that stores energy in the primary winding of a coupled inductor during the ON-time of the switch and delivers it to the secondary winding during the OFF-time. Flyback controllers fall under the broader category of AC-DC converters, which in turn belong to power management integrated circuits. Single-stage flyback topologies are widely used in LED lighting because they integrate power factor correction (PFC) and output current regulation into one power stage, reducing BOM cost and PCB area versus two-stage solutions. Key features of the XDPL8105 include integrated digital control state machine, primary-side constant-current regulation without optocoupler, >0.9 power factor at full load, adaptive dimming curve support (linear, quadratic, exponential), flicker-free operation, and built-in protection features (over-temperature, over-current, over-voltage, input under-voltage). The device supports both analog and digital dimming interfaces, making it compatible with industry-standard 0-10V and DALI control gear when paired with external interface circuitry. From an architecture standpoint, the XDPL8105 uses Infineon's XDP digital signal processor hardware engine, which executes parameter-set firmware that can be customized via the XDPL8105 graphical configuration tool. This digital core measures the primary-side current and auxiliary winding voltage to compute the secondary-side output current, achieving regulation accuracy typically within ±2% without secondary-side sensing. The 8-pin package exposes VIN, GND, CS (current sense), AUX (auxiliary winding), DRV (gate driver), DIM (dimming input), VCC, and NC pins. Typical applications for the XDPL8105 include cost-optimized LED downlights, LED panels, LED troffers, outdoor luminaires, and isolated offline LED drivers in the 5-100 W output power range. It is also suitable for flicker-free retrofit bulbs and smart-lighting front-end converters where high power factor compliance (EN 61000-3-2 Class C) is required. When designing with the XDPL8105, attention must be paid to the transformer design (leakage inductance, primary inductance, turns ratio), the snubber network selection, and the CS resistor value. The Infineon reference design RDR-704 is recommended as the starting point for any new LED driver layout. This page synthesizes distributor pricing, parametric alternatives, and practical design notes not found in the Infineon datasheet, helping engineers select, source, and implement the XDPL8105 in production LED luminaire designs.
XDPL8219XUMA1 - Flyback PFC LED Driver Controller | Infineon
The Infineon XDPL8219XUMA1 is a digital flyback controller IC with integrated Power Factor Correction (PFC), housed in a PG-DSO-8-41 package and designed for constant-voltage LED lighting and AC/DC supplies. It delivers <100 mW standby power consumption, PF >0.9 across the universal AC input range (90 Vrms to 305 Vrms), and THD <10% for enhanced harmonic compliance. The device targets Secondary-Side Regulated (SSR) constant-voltage LED driver topologies used in luminaires up to 100 mA output current capability with built-in no-dimming operation. A flyback controller is a switching power-supply control IC that regulates an isolated DC output by switching a primary-side MOSFET and using a transformer to galvanically isolate the load. Constant-voltage (CV) flyback LED drivers add an active PFC stage that shapes the input current to follow the line voltage, achieving high PF and low THD as mandated by regulatory standards such as IEC 61000-3-2. The XDPL8219 integrates PFC control directly into the flyback controller, eliminating a separate PFC stage and simplifying the BOM for cost-sensitive LED lighting designs. Key features of the XDPL8219 include an integrated 600 V high-voltage startup cell that removes the need for an external startup resistor network, secondary-side regulated constant-voltage output via digital control, and enhanced THD/PF correction algorithms that operate across a wide load range. A UART-based digital interface enables parameter tuning, in-system firmware updates, and telemetry, supporting rapid design iteration. The combination of digital control and analog PWM peripherals yields high efficiency, low standby power, and robust protection against abnormal line conditions. Technically, the controller uses Infineon's XDP (eXtremely Dense Platform) mixed-signal architecture with an embedded 8-bit core, on-chip digital compensation loops, and adaptive valley-skipping modulation for efficiency optimization at light loads. The device supports DC input voltages from 127 V to 431 V (post-rectified high-voltage DC bus), making it suitable for both AC mains-powered luminaires and DC-bus lighting such as solar or battery-fed installations. Built-in protections include over-temperature, over-current, over-voltage, and brown-out detection. Typical applications include indoor LED downlights, panel lights, ceiling luminaires, smart-home lighting fixtures, and constant-voltage AC/DC adapters where high PF, low THD, and low standby are required. The device is also used in DC-bus industrial lighting such as 24 V or 48 V architectural systems. For dimmable designs, a primary-side controlled dimming variant may be considered. When designing with the XDPL8219, pay close attention to the primary MOSFET voltage rating versus the reflected output voltage and the leakage inductance spike. The PG-DSO-8-41 package requires proper thermal copper-pour design to dissipate controller losses. Use Infineon's reference design files and the XDPL8219 design guide for transformer sizing, snubber selection, and feedback loop tuning.

XDPP1140100BXUMA1 - 32-bit Digital DC-DC Controller, VQFN-24 | Infineon
The Infineon XDPP1140100BXUMA1 is a 32-bit ARM Cortex-M0-based digital power controller optimized for DC-DC converter topologies, including hard-switched full-bridge, half-bridge, push-pull, and active-clamp forward converters. Housed in a 24-pin PG-VQFN-24-20 (4 mm x 4 mm) package, the device integrates firmware-programmable control loops, supports both PWM and LLC modulation schemes, and operates with a switching frequency up to 2 MHz. A digital power supply controller (or digital power converter controller) is a mixed-signal IC that replaces traditional analog PWM controller hardware with a programmable MCU core plus dedicated power peripherals. It belongs to the broader hierarchy of switching regulators -> DC-DC controllers -> power management ICs -> semiconductors. Digital controllers provide adaptive loop compensation, telemetry (VIN/VOUT/IIN/IOUT/TEMP), and PMBus-style configuration that analog controllers cannot match. Key features include an integrated Cortex-M0 core with on-chip nonvolatile memory for firmware, high-resolution DPWM outputs, programmable analog comparators for cycle-by-cycle protection, and integrated gate drivers for synchronous-rectifier FETs. The device supports single-phase topologies and flux balancing for multi-phase designs, while internal ADC channels monitor current, voltage, and temperature with < 1% accuracy. Communication is handled via I2C/UART/PMBus-compatible interfaces. The architecture combines deterministic hardware peripherals with a programmable firmware model, enabling platform reuse across product families. According to the Infineon datasheet, the controller's adaptive dead-time control and body-diode emulation reduce body-diode conduction losses, while per-cycle over-current protection prevents inductor saturation. The 2 MHz switching capability shrinks output filter magnetics, enabling compact, high-density power designs. Typical applications include 48 V telecom isolated bus converters, industrial 24 V input DC-DC bricks, server/crash-cart voltage regulator modules (VRMs), and battery-charging infrastructure. The wide operating range also suits renewable-energy micro-inverters and factory-automation power supplies where telemetry is required. When designing with this part, ensure firmware development follows Infineon's XDP SDK guidelines and that the exposed thermal pad is soldered to a sufficient copper pour. Avoid routing analog signal traces beneath the DPWM outputs to prevent switching-noise coupling into sensitive feedback paths.

XDPP1148100BXUMA1 - 100MHz Digital Power Controller | Infineon
The Infineon XDPP1148100BXUMA1 is a digital power supply controller based on a 100 MHz Arm Cortex-M0 core, integrating firmware-programmable control loops for advanced DC-DC and LLC converter topologies. It is offered in a 24-pin PG-VQFN-24-20 package with 4x4 mm footprint and operates from a 2.97V to 3.63V digital supply. The device is designed for high-density AI server, telecom, and 48V bus power applications where firmware-flexible digital control replaces analog PWM controller ICs. A digital power controller is an IC that executes firmware-defined control algorithms - including PID compensation, adaptive dead-time, light-load burst mode, and telemetry - in software rather than analog hardware. Architecturally it sits between the analog power stage (MOSFETs, magnetics, current shunt) and the system management controller, communicating via PMBus, I2C, or UART. The hierarchy is: power management IC -> DC-DC controller -> digital power controller. Compared to analog controllers, digital controllers deliver faster transient response, parametric tuning without hardware changes, and per-unit telemetry that improves system-level observability. Key features include the 100 MHz Cortex-M0 compute core with on-chip non-volatile firmware memory, integrated MOSFET drivers supporting hard-switched and resonant LLC topologies, adaptive dead-time and burst-mode control, and PMBus/I2C control interfaces. The 24-pin VQFN-EP package exposes multiple analog sense inputs (VOUT, ISENSE, temperature) and high-resolution digital PWMs. The XDPP1148100BXUMA1 is typically deployed as the master controller in multi-phase buck, interleaved totem-pole PFC, and full-bridge LLC stages powering 48V-to-PoL conversion in hyperscale data centers. The firmware-defined control law lets one IC cover many topologies and rails without analog IC respins. Design consideration: validate the firmware-programmed current sense gain against the actual DCR/shunt tolerance of the power stage, and respect the VQFN-EP thermal pad layout pattern (a 4x4 array of thermal vias under the EP) to keep junction temperature within the 125C operating limit.

XL4015E1 - 5A 36V 180kHz Buck DC/DC Converter | XLSEMI
The XLSEMI XL4015E1 is a 180 kHz fixed-frequency PWM buck (step-down) DC/DC converter housed in a TO-263-5 (TO263-5L) surface-mount package with an integrated power MOSFET. It delivers up to 5 A continuous load current from an 8 V to 36 V input rail, producing an adjustable output of 1.25 V to 32 V with up to 96% conversion efficiency, making it a workhorse for cost-sensitive point-of-load applications. A buck (step-down) DC/DC converter is a switch-mode power supply (SMPS) topology that uses a high-side switch, an inductor, and a capacitor to convert a higher DC input voltage into a lower regulated DC output voltage. Unlike a linear regulator, which dissipates excess voltage as heat, a buck converter stores energy in the inductor during the switch ON-time and releases it to the load during the OFF-time, achieving dramatically higher efficiency. Within the broader hierarchy, the XL4015E1 belongs to the family of integrated asynchronous buck regulators that include internal frequency compensation, a fixed-frequency PWM controller, and a power switch on a single die. Key features include a wide 8 V to 36 V input range, internally fixed 180 kHz switching frequency that balances efficiency against external L/C size, low standby current around 5 mA, internal frequency compensation that minimizes external parts, and built-in thermal shutdown and current-limit protection. The TO-263-5L (DPAK-style) package exposes the die tab for low thermal resistance when soldered to a copper pad. The architecture is a classic voltage-mode PWM controller driving an integrated N-channel MOSFET, with feedback sampling from the output via an external resistor divider. Switching at a fixed 180 kHz keeps the fundamental and harmonics away from the AM broadcast band, simplifying EMI filtering in automotive and consumer audio/video products. Efficiency peaks around 90-96% at moderate load and moderate VIN-VOUT delta; efficiency drops at very low or very high duty cycles, which is typical for asynchronous buck converters. Typical applications include 12 V / 24 V lead-acid battery step-down to 5 V or 3.3 V rails for automotive accessories, USB chargers, solar MPPT pre-regulators, LED drivers, and DIY/hobby lab power supplies. The 5-pin footprint is dimensionally similar to LM2596 but with subtly different pin functions, so any second-source design must re-verify the pinout before board layout reuse. When designing with this part, place the input ceramic bypass capacitor and the freewheeling diode as close as possible to the IC, use an inductor with low DC resistance and adequate saturation current (≥ 5 A), and provide at least 1 square inch of copper pad area under the exposed tab to keep the junction within the 125 C limit. This page synthesizes distributor pricing, verified drop-in alternatives, and practical design notes not collected on the manufacturer datasheet alone, giving engineers a single decision-ready reference.
XRP7714ILBTR-SN01-F - 4-Ch Digital PWM Controller w/ LDO | MaxLinear
The MaxLinear XRP7714ILBTR-SN01-F is a programmable quad-output digital PWM step-down DC/DC controller with an integrated standby LDO and configurable GPIO, housed in a 40-pin TQFN-EP (6x6 mm) package. The part integrates four synchronous buck channels and one linear regulator (LDO) channel, programmable through the I2C serial interface across an output voltage range of 0.9 V to 5.1 V per rail without external resistor dividers. A digital PMIC is a power management integrated circuit whose regulation loops, switching frequency, output voltage setpoints, protection thresholds, sequencing and timing are configured in firmware or non-volatile memory rather than by external analog component selection. The XRP7714 family sits in the hierarchy: PMIC > multi-output controller > digital PWM buck controller > power management IC for SoC systems, and replaces a board that would otherwise need several discrete switching controllers, an LDO, sequencers and supervisors. Key features include a 4.75 V to 25 V input range, programmable switching frequency from 300 kHz to 1.5 MHz, integrated MOSFET drivers for synchronous buck stages, 6 GPIO/ENABLE pins with 3.3 V CMOS logic (5 V tolerant), and full on-chip protection (over-voltage, under-voltage, over-current, and thermal shutdown). Each rail is independently programmable for soft-start, ramp rate, sequencing and fault response, which makes the IC attractive as a one-chip power tree for FPGAs, DSPs and microprocessors. The architecture is built on four independent Digital Pulse-Width Modulator (DPWM) channels with per-channel current-mode control loops, an internal reference and a precision LDO for standby/auxiliary rails. The integrated drivers and small 40-pin TQFN-EP footprint allow a 4-rail + LDO solution in roughly 25 mm x 25 mm of board area including passives, materially smaller than an equivalent analog implementation. Typical applications are FPGA/SoC core and IO rails, networking and telecom boards, industrial controllers and embedded computing platforms where sequencing, monitoring and a small BOM matter more than absolute conversion efficiency. Designers choose this controller when rails must be re-configurable across SKUs or when a single PMIC replaces several discrete regulators. When designing with this part, follow MaxLinear reference design guidance for output LC selection at the chosen switching frequency, place the IC on a thermally adequate copper pour, and use the GUI / I2C tools to program default output voltages and fault thresholds. The SN01-F suffix denotes a specific factory configuration and NVM image; verify the default output setpoints against the system requirements before re-programming in production. This page combines verified distributor pricing, MaxLinear datasheet parameters, drop-in alternatives and practical design notes not gathered in any single manufacturer document, giving engineers a faster path from selection to qualified BOM.
ZXGD3009DYTA - 40V 1A Low-Side Gate Driver SOT-363 | Diodes Inc
The Diodes Incorporated ZXGD3009DYTA is a 40V, 1A low-side non-inverting gate driver IC housed in a 6-pin SOT-363 (SC-88) surface-mount package, designed to switch MOSFETs rapidly in high-current power-conversion stages. The device is a high-gain emitter-follower buffer that delivers typically 500 mA into a low-impedance MOSFET gate from only 10 mA of input drive current, and it provides separate source and sink outputs so turn-on and turn-off transitions can be tuned independently with external resistors. A gate driver is a specialized buffer/amplifier placed between a low-power controller (MCU, PWM IC, gate-driver logic output) and the gate of a power MOSFET, IGBT, or GaN transistor. Without such a buffer, the controller output cannot source or sink enough instantaneous current to charge and discharge the gate's Miller capacitance quickly, resulting in slow edges and high switching loss. Gate drivers sit in the broader hierarchy: gate driver -> MOSFET/IGBT driver -> power management IC -> semiconductor. Key specifications of the ZXGD3009DYTA include a wide VCC range that minimizes on-state losses, near-zero quiescent current, an emitter-follower output topology that is rugged against latch-up and shoot-through, and an optimized SOT-363 pin-out that simplifies PCB layout and reduces parasitic trace inductance. The separate Q1 (source) and Q2 (sink) outputs let the designer program asymmetric rise and fall times for EMI control or for paralleled-MOSFET sharing. The ZXGD3009DYTA's emitter-follower architecture is intrinsically simple and tolerant of wide supply rails; it avoids the cross-conduction concerns of totem-pole CMOS drivers. It is commonly used as a low-side switch driver in DC-DC converters, motor-control half-bridges, hot-swap controllers, solenoid and relay drivers, and class-D audio output stages where gate-charge slew control is critical. Typical applications include PFC boost stages, synchronous-rectifier drivers in SMPS, and high-current load switches in industrial and telecom power systems. By tailoring source and sink resistors the designer can deliberately slow the turn-on edge to control ringing or speed up the turn-off edge to minimize dead time. When designing with this part, place the gate-drive resistors as close to the Q1/Q2 pins as possible and keep the high-current gate loop area minimal to suppress parasitic inductance. Verify that the controller's logic output can swing within the driver's input common-mode range, and add a small base resistor on the input if the source impedance is too low to set a defined input current.

ZXMS6004DN8-13 - Dual 60V 1.3A Self-Protected N-FET IntelliFET | Diodes Inc
The Diodes Incorporated ZXMS6004DN8-13 is a dual self-protected low-side N-channel MOSFET IntelliFET with logic-level input, housed in an 8-pin SO (SO-8) package. Each of the two integrated FETs is rated at 60 V drain-to-source, 1.3 A continuous drain current, and a typical on-resistance of 0.5 ohm, providing robust switching for inductive loads driven by 3.3 V or 5 V microcontrollers. The device integrates over-temperature, over-current, over-voltage (active clamp), and ESD protection on the logic-level input, replacing a discrete MOSFET plus Zener-Diac clamp with a single 8-pin IC. An IntelliFET (Intelligent FET) is a self-protected low-side power switch that combines an N-channel enhancement-mode MOSFET with on-chip protection circuits in one package. It belongs to the smart power switch family within power-management semiconductors, sitting hierarchically above discrete MOSFETs but below fully featured half-bridge motor drivers. The "self-protected" attribute means the IC can survive common fault conditions (short to battery, short to ground, inductive flyback, ESD strikes) without external TVS diodes or sense resistors, simplifying PCB design in harsh automotive and industrial environments. Key features include dual independent 60 V / 1.3 A channels, 0.5 ohm typical RDS(on) at VGS=5 V, integrated active clamp at 60 V, 120 mJ avalanche energy rating, over-temperature shutdown, over-current limiting, and 8 kV HBM ESD protection on the input pin. The logic-level gate is driven directly from a 3.3 V or 5 V GPIO without requiring a gate driver, which is essential for low-pin-count microcontrollers. The SO-8 package provides a thermal resistance of approximately 80 C/W (per datasheet) and operates from -40 C to +125 C junction temperature. Architecturally, each channel consists of a vertical N-channel DMOS output stage plus a protection state machine that monitors drain current, junction temperature, and drain-source voltage. The active clamp limits VDS to 60 V during inductive turn-off, allowing direct driving of solenoids, relays, and small DC motors without freewheeling diodes. The two channels share only the package and ground pins, enabling independent PWM control of two loads with separate diagnostic capability. Typical applications include 12 V automotive lamp and LED driver circuits, solenoid and valve drivers in HVAC and industrial controls, relay replacement in PLCs, small brushed DC motor drivers in robotics and white goods, and general low-side switching from microcontroller I/O. The wide 60 V rating also tolerates 24 V industrial bus transients. When designing with this device, ensure the total power dissipation (I2 * RDS(on) per channel plus switching losses) does not exceed the SO-8 thermal budget. For continuous 1 A loads on both channels simultaneously, a 1 oz copper pour of at least 100 mm^2 connected to the SO-8 thermal pad area is recommended. The two channels are not internally bonded; each gate must be driven independently.
