Test Procedure for the NCP5106B Evaluation Board 6/6/2007 A Vac A V V J2 jumper Table 1: Required Equipment AC power source can be able to deliver 230Vrms or 110Vrms 1 resistive load: 200 Ω / 50 W two volt-meters two ampere-meters One NCP5106B Evaluation Board Test Procedure: 1. First of all check if you need or not the jumper #2 (J2 on the board close the diode bridge). This jumper must be removed in case of European mains (230 Vac input voltage) and have to placed in case of US mains (110 Vac). This jumper is used to build a voltage doublers just after the bridge diode in case of US mains input voltage range. 2. Connect the test setup as shown above: • AC source • Voltmeter and Ampere meter on the load • Load on the output 3. Apply 230 Vac if European mains or 110 Vac for the US mains on the input connector. Rload 200Ω 4. Compare Iload and Vload with the following table according your input mains voltage. 5. If you get the correct output and input voltage, you can now connect a 36 W fluorescent tube on the output (see the ballast connection figure). Test results: Input mains J2 European Removed Yes Î max input voltage: 132 Vrms US Vin (Vrms) 230 V Iin (Arms) 278 mA Vload (Vrms) 303 V Iload (Arms) 370 mA 110 V 514 mA 263 V 340 mA Input connection A Vac 36 W Tube V Output connection Figure 1: Ballast connection
