Test Procedure for the NCV8871BSTGEVB Evaluation Board Equipment: 1. Power Supplies (1 High Power, 1-3 Logic Level) 2. Digital Volt Meter 3. Digital Ampere Meter 4. Function Generator (optional) Test Procedure: 1. Apply 13.2 V to VIN. The output voltage should be around 13 V. 2. Apply 5 V to the EN/SYNC pin. The output voltage should be around 18 V. 3. Attach a 9 Ω load to the output. It should draw 2 A, and the output voltage should be around 18 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 18 V. 6. Look at the switch node. The frequency should be 200 kHz. 7. End of test. 12/9/2011 -1- www.onsemi.com
