Equipment needed

Test

• Power Supply

• Digital Volt Meter

• Digital Amp Meter

1. Jumper ENABLE should be open.

2. Jumper SELECT should be closed to 1.2V.

3. Set the power supply to 3.6V and the current limit of at least 800mA.

4. Connect the power supply connector to connectors VIN+ and VIN-. The DC current

5. Close ENABLE connector. The DC current measurement on VIN line should be around

6. Measure the output voltage between VOUT+ and VOUT- connectors. You should see

7. Remove the ENABLE jumper. The DC current measurement on VIN line should be back

measurement on VIN line should be around 0.3µA.

40µA.

around 1.2V voltage operation.

around 0.3µA.
