ISL62883EVAL2Z User Guide

Application Note July 13, 2009

Introduction

The ISL62883EVAL2Z evaluation board demonstrates the performance of the ISL62883 multiphase synchronous-buck PWM V

controller implementing Intel IMVP-6.5

CORE

protocol. The ISL62883 features Intersil's Robust Ripple Regulator (R

3

) 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 V

and PGND.

Jumper Descriptions

• J1: Set the ISEN2 pin configuration. ISEN2 can be connected to the power stage, tied to +5V, GND or left floating. Connect ISEN2 to the power stage when the ISL62883 is configured for 3-phase or 2-phase application. Tie ISEN2 to 5V when the ISL62883 is configured for 1-phase application.

• J2: Set the ISEN1 pin configuration. ISEN1 can be connected to the power stage, tied to +5V, GND or left floating. Connect ISEN1 to the power stage when the ISL62883 is configured for 3-phase, 2-phase application. Leave ISEN1 floating when the ISL62883 is configured for 1-phase application

• J3: If installed, the ISEN3/FB2 pin will be connected to the power stage. If uninstalled, the ISEN3/FB2 pin will be disconnected from the power stage. Install J3 when the ISL62883 is configured for 3-phase application. Uninstall J3 when the ISL62883 is configured for 2-phase or 1-phase application.

• J4: Set the PWM3 pin configuration. PWM3 can be connected to the ISL6208 driver, tied to +5V, GND or left floating. Connect PWM3 to the ISL6208 driver when the ISL62883 is configured for 3-phase application. Tie PWM3 to 5V when the ISL62883 is configured for 2-phase or 1-phase application.

• J16: If installed, the +5V rail supplies the +3.3V rail to the auxiliary circuit on the board. DO NOT APPL Y +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 TP/37/TP30.
