NCP1522B - BILL OF MATERIAL
Designator
VIN, VOUT
1. Jumper ENABLE should be open.
2. Jumper SELECT should be closed to 1.2 V.
3. Set the power supply to 3.6 V and the current limit of at least 800 mA.
4. Connect the power supply connector to connectors V
5. Close ENABLE connector. The DC current measurement on Vin line should be around 55 mA.
6. Measure the output voltage between V
7. Remove the ENABLE jumper. The DC current measurement on Vin line should be back around 0.3 mA.
