XDPE132G5H-G000 - Infineon Technologies

概要

XDP™ 16-phase dual loop PWM digital multiphase controller

The XDP™ XDPE132G5H is a digital multi-phase buck controller that can be configured in either a single loop or dual loop mode with a feature set optimized to support high performance processors that require AVSBus, AMD SVI2, or nVIDIA PWMVID. It can support up to 16 phases and allows flexible phase assignment between the two loops.

The XDPE132G5H includes efficiency shaping technology to deliver exceptional efficiency at minimum cost across the entire load range. The XDPE132G5H offers digitally programmable load line thereby eliminating the need for any external load line setting components. The controller is designed to work with Infineon’s internal current sense OptiMOS™ Power Stages and provides accurate input and output current reporting.

A unique Adaptive Transient Algorithm (ATA), based on proprietary non-linear control algorithms provides excellent transient response with reduced output capacitance.

The I2C/PMBus interface can communicate with up to 127 XDPE132G5H-based controllers. Device configuration and fault parameters are easily defined using the OpenPower GUI and stored in on-chip memory.
