Test Procedure for the NCL30085FLYGEVB Overview This procedure describes the functional testing of the NCL30085FLYGEVB and NCL30088FLYGEVB LED driver using a flyback PFC. Basic Specifications Input Voltage – 90 V ac to 265V ac Input Frequency – 50/60 Hz Output Voltage – 14 V dc to 28 V dc Output Current –350 mA dc Nominal 8/7/2014 1 www.onsemi.com Equipment Needed AC Source – 90 V ac to 265 V ac 50/60 Hz Minimum 1A ac capability AC Wattmeter – 30 W Minimum, True RMS Input Voltage and Current, Power Factor 0.2% accuracy or better DC Voltmeter – 200 V dc minimum 0.1% accuracy or better DC Ammeter – 0.5 A dc minimum 0.1% accuracy or better LED Load – 14 V dc to 28 V dc rated for at least 1000 mA dc operation Test Set Up 1. Connect the Unit Under Test (UUT) per the test set up in Figure 1. AC Power Source AC Wattmeter UUT DC Ammeter DC Voltmeter LED Test Load Figure 1. Test Set Up Note: Unless otherwise specified, all voltage measurements are taken at the terminals of the UUT. Functional Test Procedure NCL30085FLYGEVB Connect the UUT per figure 1. Test Limits Min Max Pass / Fail (Circle One) Test Condition Test Variable Vin = 90 V ac Vout = 28 V dc Vin = 120 V ac Vout = 28 V dc Vin = 265 V ac Vout = 28 V dc Vin = 265 V ac Vout = 28 V dc Vin = 120 V ac Vout = 28 V dc Output Current 332mA 368mA Pass / Fail Output Current 332mA 368mA Pass / Fail Output Current 332mA 368mA Pass / Fail Power Factor 0.90 8/7/2014 Input Power Pass / Fail 13W 2 Pass / Fail www.onsemi.com Step Dimming Test Procedure Connect the UUT per figure 1 with an LED Load between 20 – 28 V dc. Apply 120 V ac and verify that the current is 332 – 368 mA. Interrupt the AC input for 1 – 2 seconds. Verify that the current has stepped down. Repeat the previous step 2 more times each time verifying that the current has stepped down. Note: the current steps are large and should be evident to the casual observer. Interrupt AC input once more and verify that the current returns to the full output 332 – 368 mA. Mark the Appropriate Version after test 8/7/2014 3 www.onsemi.com
