Application Note 1485 ISL95210 10A Integrated FET Regulator Evaluation Board Setup Procedure Quick Setup Guide This document describes the setup procedure for the ISL95210EVAL1Z Rev B board. Step 1: Set the +5.0V power supply to +5V and place in the “STANDBY” or “OFF” position. Connect the positive terminal (+) of the supply to the +5V terminal TP4 and the negative terminal (-) of the supply to GND TP3. Step 2: Connect the positive terminal (+) of the electronic load to the VOUT terminal TP1. Connect the negative terminal (-) of the electronic load to the GND terminal TP2. Make sure the electronic load is set to the 0A condition. Step 3: Check to ensure all jumpers and switches are in their default positions prior to application of power (refer to “Detailed Description of Switch Settings” and “Detailed Description of Jumper Settings” on page 2). Step 4: Set the power supply to the “ON” position. LED D1 should show Red. Check all power supply outputs with a DMM to ensure correct voltage levels. Adjust if necessary. • ISL95210 Data Sheet Step 5: • ISL95210 Evaluation Board Setup Procedure (this document) Move the ENABLE jumper to the “ON” position. LED D1 should show Green. Step 6: Measure VOUT with a DMM from TP5(+) to TP8(-). It should read 1.2V (±1%). What’s Needed At this point, the board has been properly powered up. Normal testing can begin. The Evaluation Board Kit contains the following materials: • ISL95210EVAL1Z REV B Board • Precision Digital Multi-Meter • Electronic Load • 4-Channel Oscilloscope NOTE: Amperage rating of power supplies are determined by maximum expected loading plus a percentage margin of error.

To that end, Intersil introduces the ISL95210 regulator. It features integrated power MOSFET switches that are capable of delivering 10A continuous load current at elevated temperatures and maintaining high efficiency. Leveraging a highly digital feature set and the new R4™ modulator allows the ISL95210 to provide a fully regulated point of load solution with only four external components.
