XDPE152C4D0000XUMA1

The Infineon Technologies XDPE152C4D0000XUMA1 is a digital multi-phase controller featuring a 12-phase dual-loop voltage regulator architecture. It is designed to provide core voltage regulation for Intel VR13, VR13HC, and VR14 based microprocessors found in servers and workstations.

This controller integrates a high-performance analog front end with a programmable ARM Cortex-M0 processor. It supports flexible phase configuration, allowing for allocations such as 12+0, 11+1, 10+2, 8+4, or 6+6 phases across its two loops. The output voltage regulation range is from 0.25 V to 1.52 V (5 mV/step) and 0.5 V to 3.04 V (10 mV/step).

Key features include compliance with Intel VR13, VR13HC, VR14 specifications, as well as Intel SVID and PMBus Rev 1.3.1. It offers extensive fault detection and protection capabilities, including overvoltage, undervoltage, and overcurrent protection. The device is housed in a 48-lead QFN plastic package suitable for surface mounting.

Applications include Vcore power regulation for Intel processors in servers, workstations, and high-end desktops, as well as high current ASIC and PMBus POLs. The controller utilizes a digitally controlled phasing for flexibility and digital current emulation for TLVR inductor support.
