Test Procedure for the NCL30083FLYGEVB Evaluation Board Equipment Needed AC Source – 100 to 265 V ac 50/60 Hz Minimum 1 A ac capabilities AC Wattmeter – 30 W Minimum, True RMS Input Voltage and Current, Power Factor 0.2% accuracy or better DC Voltmeter – 100 V dc minimum 0.1% accuracy or better DC Ammeter – 1 A dc minimum 0.1% accuracy or better LED Load o Flyback – 14 – 17 V dc – 5 LED Load @ 500 mA o Buck Boost – 50 – 55 V dc – 15 LED Load @ 200 mA Test Connections 1. Connect the Unit Under Test (UUT) per the test set up in Figure below. AC Power Source AC Wattmeter UUT DC Ammeter DC Voltmeter LED Test Load Figure: Test Set Up 2. Set the AC source to 120 ±1 V ac RMS 60 Hz or 230 ±2 V ac RMS 50 Hz. Note: Unless otherwise specified, all voltage measurements are taken at the terminals of the UUT.

Connect the UUT to the LED load. 2. Apply 120 V ac power. 3. Verify that the output current is within the regulation limits as specified in the functional test procedure. 4. Interrupting the AC input for 1-2 s will step the output current down. 5. There 6 discrete current levels. After the lowest level, the current will return to maximum output. 6. Cycle the input power 6 times validating that the current steps down at each cycle and returns to maximum. 6/1/2013 2 www.onsemi.com
