Test Procedure for the NCP1060BUCKGEVB The following steps detail the test procedure for all these boards: Necessary Equipment: 1 Current limited 90 ÷ 265Vrms AC source (current limited to avoid board destruction in case of a defective part) (e.g. AGILENT 6811) 1 AC Volt-Meter able to measure up to 300V AC. (e.g. KEITHLEY 2000) 1 AC Amp-Meter able to measure up to 3A AC. (e.g. KEITHLEY 2000) 4 DC Volt-Meter able to measure up to 50V DC. (e.g. KEITHLEY 2000) 4 DC Amp-Meter able to measure up to 5A DC. (e.g. KEITHLEY 2000) 4 DC Electronic Load 0 - 60A (e.g. AGILENT 6060B) AC Source 90 ÷ 265Vac A V A V DC LOAD 12V / 150 mA Figure 1: Test Setup for Buck Convertor Test Procedure (Buck convertor): 1. Connect the test setup as shown in Figure 1. 2. Apply an input voltage, Uin =90 - 265Vac 3. Apply Iout(load) = 0A 4. Check that Uout is no higher than 15V 5. Increate Iout(load) load to: 150 mA 6. Check that Uout is 12V 7. Power down the load 8. Power down Uin 9. End of test 01/27/2015 1 www.onsemi.com
