Test Procedure for the NV890200PDR2GEVB Evaluation Board
Required Equipment
2 x DC voltage source
1 x DC electronic load
2 x Multimeters
Test Procedure:
1. Connect the test setup as shown above.
2. Make sure the load is not enabled.
3. Apply enable voltage VEN=0V. Apply an input voltage, VIN = 13.2 V. VOUT should be 0V.
4. Apply enable voltage VEN=3V. Verify that the output voltage is 3.3 V +/-0.15 V.
5. Set up the load to 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 3.3 V +/-0.15 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.
