Test Procedure for the NCP382HD10AAGEVB Evaluation Board Equipment Needed: 1. Power Supply (5V, 3A) 2. Potentiometer/Load (100Ω, 10W) 3. Multimeter Note: Cables should be as short as possible to lower their inductance value – otherwise you may harm either the input or output pins of the device Set-up & Test: 1. 2. 3. 4. 5. 6. 7. Apply Vin = 4V dc (Over Current Limit = 1A) on IN test point. Connect a 100Ω, 10W load between Output1 test point and GND strap. Toggle EN1 strap between Low and High sides. Output1 must change from 0 to 4V by toggling the EN1 switch. Disconnect load from Output1 and connect it to Output2 test point. Toggle EN2 strap between Low and High sides. Output2 must change from 0 to 4V by toggling the EN2 switch. 7/30/2012 -1- www.onsemi.com
