Single-Phase PWM Regulator Evaluation Board for IMVP-6.5™ Mobile CPUs and GPUs

ISL62881CCPUEVAL2Z User Guide

Overview

The ISL62881CCPUEVAL2Z evaluation board is used to demonstrate the performance of the ISL62881C single-phase synchronous-buck PWM GPU VCORE controller implementing the Intel® IMVP-6.5™ protocol. The ISL62881C features Renesas' Robust Ripple Regulator (R3™) technology. An on-board dynamic-load generator is included for evaluating the transient-load response. It applies a 300µs pulse of approximately 0.2Ω load across VO and PGND.
