11/1/2013 Test Procedure for the NCP45520IMNGEVB Evaluation Board 1. Ensure jumpers J1 and J7 are placed (i.e. pins 1 and 2 of J1 and J7 headers are shorted) on evaluation board 2. Connect DC Power Supply to VCC and GND (max voltage = 5.5V, current limit > 1mA) 3. Connect DC Power Supply to VIN and GND (max voltage = 13.5V, current limit > 1A) 4. Connect DC Load to VOUT and GND 5. Set VCC voltage to 3.3V and turn on Power Supply 6. Set VIN voltage to 12V and turn on Power Supply 7. Enable Load Switch by applying voltage to EN (must be > 2V, but not exceed VCC voltage) 8. Set VOUT load to 1A and turn on DC Load 9. Measure voltage at VOUT using the VOUT Kelvin Connection test point a. Should measure within 40mV of the VIN voltage, referenced from the VIN Kelvin Connection test point 10. Measure voltage at PG test point a. Should measure approximately VCC voltage 11. Turn off DC Load connected to VOUT 12. Disable Load Switch by removing voltage on EN (can float EN or tie to GND) 13. Measure voltage at VOUT using the VOUT Kelvin Connection test point a. Should measure approximately GND 14. Measure voltage at PG test point a. Should measure approximately GND
