Description

The ISL97656IRTZEVALZ is an evaluation kit for evaluating

the ISL97656, a step-up voltage regulator that operates with

high frequency and high efficiency. This evaluation kit is

designed to deliver up to 2A output current for portable

equipment and TFT-LCD display.

The ISL97656IRTZEVALZ evaluation kit provides a dip

switch that allows users to select either 620kHz or 1.2MHz

frequency.

Key Features

• A Complete Evaluation Platform for the ISL97656

• Input Voltage: 2.3V to 5.5V

• Proven Evaluation Board Layout

• Pb-Free (RoHS Compliant)

What is Needed

The following instruments will be needed to perform testing:

• Power Supplies

• DC Electronic Load

• Multimeters

• Oscilloscope

• Cables and Wires

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

Quick Setup Guide

Maximum Output Current

The MOSFET current limit is normally 4A and guaranteed

3.8A. This restricts the maximum output current that the

ISL97656 can drive.Table 1 shows typical maximum I

values for 1.2MHz switching frequency and 10µH inductor.

1. Connect power supply between headers of V

2. Connect E-load between headers of V

3. Close pins 1 and 4 of S1 to tie FREQ pin to V

4. Close pins 2 and 3 of S1 to tie EN pin to V

5. Make sure all the connections on the evaluation board

be connected to V

between 2.3V and 5V, and current limit at 4A.
