Test Procedure for the NCV890131 DEMO BOARD REV 1.0 IOUT Multimeter VIN DC electronic Load Multimeter VOUT VEN Required Equipment 2 x DC voltage source 1 x DC electronic load 2 x Multimeters Rev 1.0 Page 1 March 1, 2013 Test Procedure: 1. Connect the test setup as shown above. 2. Make sure the load is not enabled. 3. Apply an enable voltage VEN=0V. Apply an input voltage, VIN = 13.2 V. VOUT should be 0V. 4. Apply an enable voltage VEN=3V. Verify that the output voltage is 3.3 V +/-0.15 V. 5. Set up the load to 1.2A and enable it. Verify that the output voltage is still 3.3 V +/-0.15 V. 6. Change the input voltage to 36 V. Verify that the output voltage is 0 V. 7. Change the input voltage to 6 V. Verify that the output voltage is 3.3 V +/-0.15 V. 8. Change the input voltage to 3.9 V. Verify that the output voltage is 0 V. 9. Change the input voltage to 6 V. Verify that the output voltage is 3.3 V +/-0.15 V. 10. Apply an enable voltage VEN=0V. VOUT should be 0V. 11.Turn off the DC sources. Rev 1.0 Page 2 March 1, 2013
