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

ISL62882CEVAL2Z User Guide

Overview

The ISL62882CEVAL2Z evaluation board is used to demonstrate the performance of the ISL62882C multiphase synchronous buck PWM VCORE controller, implementing the Intel® IMVP-6.5™ protocol. The ISL62882C 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 25mΩ load across VO and PGND.
