Test Procedure for the NCP1399AIOGEVB Evaluation Board Figure 1: Test Setup The following steps describe the test procedure for all these boards: Required Equipment: Current limited AC Power Supply (e.g. AGILENT 6811B) ................................ DC Volt-Meter able to measure up to 60 V DC (e.g. KEITHLEY 2000) ............ Shunt Resistor - Rsense (e.g. 150 mV/20 A) ..………………............................ DC Electronic Load (e.g. AGILENT 6060B) ...................................................... Watt-Meter (e.g. Yokogawa WT210) ……………………………………………… AC voltage Switch 260 Vac/3 A ………………………………………………….… DC voltage Switch 12 Vdc/20 A ………………………………………………….… 1pc 2pc 1pc 1pc 1pc 2pc 1pc Test Procedure: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. Connect the test setup as shown in Figure 1. Turn on Switches SW2 and SW3 Turn off Switch SW1 Apply I OUT (load) = 20 A Apply an input voltage, V IN = 110 Vac Check that V OUT = 12 ± 0.3 Vdc Check efficiency that Eff > 88% Set I OUT to 10 A Check efficiency that Eff > 88% Set I OUT to 1 A Check efficiency that Eff > 55% Increase an input voltage V IN = 230 Vac Turn off Switches SW2 and SW3 Turn on Switch SW1 Wait 30 minutes Check no-load input power consumption (integrate input power for 10 minute) that Pin < 150 mW 17. Turn off V IN 18. End of the test 3/10/2014 1 www.onsemi.com
