Product details
Overview
XDPE132G5DG000XUMA1 from Infineon Technologies is a digital multiphase PWM controller IC for high-performance CPU/GPU VRMs, supporting up to 8-phase operation with adaptive voltage positioning (AVP), 0.3–1.8 V output range, and 400 kHz–1 MHz switching frequency. It integrates PMBus 1.3 interface, telemetry monitoring, and supports Intel VR13/VR13.HC specifications in server and workstation power delivery.
For engineers reviewing the XDPE132G5DG000XUMA1 datasheet, XDPE132G5DG000XUMA1 pinout, XDPE132G5DG000XUMA1 application, or XDPE132G5DG000XUMA1 equivalent, key selection factors include phase count scalability, AVP compliance, PMBus programmability, thermal loop response time, and VR13.HC timing accuracy under transient load steps.
Technical Context
This controller implements a dual-loop digital control architecture: an outer voltage loop with AVP compensation and an inner current-loop per phase using real-time phase current sensing via integrated ΔΣ ADCs. It supports dynamic phase shedding, DVID, and seamless transition between active and sleep states.
Configuration is performed via PMBus commands (e.g., VOUT_COMMAND, READ_VOUT, READ_IOUT) with full telemetry including temperature, voltage, current, and fault status. The device operates across –40°C to +125°C junction temperature and requires external gate drivers for MOSFET control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Phase Support | Up to 8 phases; enables scalable high-current VRM designs for CPUs up to 300 A. |
| Output Voltage Range | 0.3 V to 1.8 V; covers core voltage requirements for modern x86 and AI accelerators. |
| Switching Frequency | 400 kHz to 1 MHz; balances efficiency vs. component size in high-density server PCBs. |
| PMBus Compliance | PMBus 1.3; allows full configuration, telemetry readback, and fault logging via standard system management bus. |
| AVP Support | Adaptive Voltage Positioning per Intel VR13/VR13.HC spec; reduces output capacitance by dynamically adjusting VOUT based on load current. |
| Operating Temp | –40°C to +125°C TJ; qualified for enterprise server and edge AI inference chassis environments. |
Pinout & Package
XDPE132G5DG000XUMA1 is housed in a 64-pin QFN package (9 mm × 9 mm, 0.5 mm pitch) with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | Digital I/O supply | 3.3 V supply for PMBus interface and logic; must be decoupled locally. |
| VDDA | Analog supply | 3.3 V analog rail for ADCs and reference circuits; separate filtering required. |
| PHASE[0:7] | Phase current sense inputs | Differential inputs for external current-sense resistors per phase; supports bidirectional sensing. |
| SCL / SDA | PMBus interface | Open-drain I²C-compatible bus pins; require pull-up resistors to VDDIO. |
| EN | Enable input | Active-high enable; synchronous startup sequencing with other VRM components. |
| PGOOD | Power-good output | Open-drain signal indicating regulated output within ±1% tolerance and no faults. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-loop digital control | Independent voltage and per-phase current regulation enables fast transient response (<5 µs) and precise current balancing. |
| Dynamic phase shedding | Automatically disables unused phases under light load to improve efficiency at <20% load without compromising stability. |
| VR13.HC timing compliance | Meets Intel's strict tVRD, tVRR, and dV/dt requirements for high-current GPU and CPU cores. |
| Real-time telemetry | Continuous reporting of VOUT, IOUT, temperature, and fault flags via PMBus-no external ADC or monitoring IC needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiphase VRM controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL99390R5245 | 6-phase max, no native AVP; relies on external compensation network for voltage positioning. | Targeted at mid-tier client platforms; lacks VR13.HC timing certification. | Choose when cost sensitivity outweighs VR13.HC compliance and telemetry depth. |
| MP2965GQZ | 8-phase, PMBus 1.3, but uses analog current-mode control instead of digital dual-loop; no real-time per-phase current reporting. | Used in embedded industrial controllers where deterministic latency > telemetry granularity. | Prefer when deterministic control loop timing is prioritized over configurability and telemetry bandwidth. |
Compared with ISL99390R5245 and MP2965GQZ, XDPE132G5DG000XUMA1 uniquely delivers certified VR13.HC timing, per-phase current telemetry, and adaptive voltage positioning in a single digital controller-enabling higher power density and reduced BOM count in AI and server VRMs.

FAQ
What is the maximum supported phase count for XDPE132G5DG000XUMA1?
XDPE132G5DG000XUMA1 supports up to 8 synchronous buck phases. It provides dedicated differential current-sense inputs (PHASE[0:7]) and phase-enable outputs to drive external gate drivers. Phase count is configured via PMBus command PHASE_NUM, and the controller automatically adjusts loop compensation and current balancing algorithms accordingly.
Does XDPE132G5DG000XUMA1 require external gate drivers?
Yes, XDPE132G5DG000XUMA1 does not integrate high-current gate drivers. It outputs low-voltage logic-level phase control signals (e.g., PHx_H, PHx_L) that must interface with external half-bridge or high-side/low-side gate driver ICs such as IRS2007 or 2EDN7534.
Can XDPE132G5DG000XUMA1 operate without PMBus communication?
Yes-it supports autonomous operation using factory-programmed default settings stored in internal OTP memory. PMBus is optional for configuration, telemetry, and dynamic adjustment; all critical functions (startup, regulation, fault protection) operate independently of bus activity.
What thermal management features does XDPE132G5DG000XUMA1 include?
The device integrates a die-temperature sensor with ±3°C accuracy and supports thermal throttling via PMBus command TEMP_LIMIT. It also monitors external NTC thermistors connected to THRM pins and can trigger PGOOD deassertion or phase shedding when thresholds are exceeded.
