Test Procedure for the NCP1063BUCKGEVB Evaluation Board Necessary Equipment: • • • • • 1 Current limited 90 ~ 264Vrms AC source (current limited to avoid board destruction in case of a defective part) (e.g. KIKUSUI PCR500M) 1 Power Meter (e.g. YOKOGAWA WT210) 1 DC Volt-Meter able to measure up to 50V DC. (e.g. Agilent 34401A) 1 DC Amp-Meter able to measure up to 5A DC. (e.g. Agilent 34401A) 1 DC Electronic Load 0 - 60A (e.g. Chroma 6312A with 63115A Module ) 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 - 264Vac 3. Apply Iout(load) = 0A 4. Check that Uout is no higher than 15V 5. Increate Iout(load) load to: 350 mA 6. Check that Vout is 12V 7. Power down the load 8. Power down Vin 9. End of test 05/28/15 1 www.onsemi.com
