NCP10672B15GEVB ON Semiconductor

Test Procedure for the NCP10672 demo boards 11/27/2018 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 20V DC. (e.g. KEITHLEY 2000) 4 DC Amp-Meter able to measure up to 500 mA DC. (e.g. KEITHLEY 2000) 4 DC Electronic Load 0 - 1A (e.g. AGILENT 6060B) DC LOAD V 15 V / 270 mA A AC Source A V 90 265 V ac Figure 1: Test Setup for 15 V Buck Converter Test Procedure (Flyback 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 Maximum 16 V 5. Increate Iout(load) load to: 270 mA 6. Check that Uout is 15 V 7. Power down the load 8. Power down Uin 9. End of test DC LOAD V 5 V / 50 mA A A AC Source V 90 265 V ac Figure 2: Test Setup for 5 V Buck Converter 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 Maximum 6 V 5. Increate Iout(load) load to: 50 mA 6. Check that Uout is 5 V 7. Power down the load 8. Power down Uin 9. End of test
