Test Procedure for the NCV8871LVBGEVB Evaluation Board Equipment Needed Power Supplies (1 High Power, 1-3 Logic Level) Digital Volt Meter Digital Ampere Meter Function Generator (optional) NCV8871LWB Test Procedure: 1) Apply 8 V to VIN. The output voltage should be around 7 V - 8 V. 2) Apply 5 V to the EN/SYNC pin. The output voltage should be around 10.6 V. 3) Attach a 10 Ω or 11 Ω load to the output. It should draw 1 A, and the output voltage should be around 10.6 V. 4) Look at the switch node. The frequency should be around 170 kHz. 5) Apply a 200 kHz, 5 Vpp clock to the EN/SYNC pin. The output voltage should be around 10.6 V. Look at the switch node. The frequency should be 200 kHz. 11/16/2012 -1- www.onsemi.com
