ISL62881CGPUEVAL2Z Evaluation Board User Guide

Hardware Description

The ISL62881CGPUEVAL2Z evaluation board

demonstrates the performance of the ISL62881C

single-phase synchronous-buck PWM GPU VCORE

controller implementing Intel IMVP-6.5 protocol. The

ISL62881C features Intersil's 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 0.2Ωload across

VOand PGND.

Jumper Descriptions

• J16: If installed, the +5V rail supplies the +3.3V rail

to the auxiliary circuit on the board. DO NOT APPLY

+3.3V TO TP37/TP30 WHILE J16 IS

INSTALLED! IT’LL SHORT THE +5V AND THE

+3.3V POWER SUPPLIES. When measuring board

efficiency, uninstall J16 and apply +3.3V to

TP37/TP30.
