Test Procedure for the NCP5181 Evaluation Board 15-Feb-06 A A Vac V V J2 jumper Table 1: Required Equipment AC power source can be able to two volt-meters deliver 230Vrms or 110Vrms One NCP5181 Evaluation Board 1 resistive load: 200 Ω / 50 W Test Procedure: two ampere-meters Rload 200Ω 1. First of all check if you need jumper #2 (J2 on the board close the diode bridge). This jumper must be removed for use with European mains (230 Vac input voltage), and must be in place when using US mains (110 Vac). This jumper is used to build a voltage doubler just after the bridge diode in case one is using US mains input voltage range. 2. Connect the test setup as shown above: • AC source • Voltmeter and Ampmeter on the load • Load on the output 3. Apply 230 Vac for European mains or 110 Vac for US mains on the input connector. 4. Check Iload and Vload with the appropriate value in the table below. 5. If you get the correct output and input voltage, you can then connect a 36 W fluorescent tube on the output (see the ballast connection figure).
