4. Measure VBUS OUT = 5V
5. Measure VIN current consumption: Typical 20µA, Max 35µA
6. Measure FLAG pin > 1.2V.
7. Connect EN strap on left side
8. Check Vout < 0.3V (wait C2 cap discharge, few second )
9. Check is still FLAG pin > 1.2V
Turn Off sequence.
1. Turn off Vin supply. Disconnect.
2. Turn off Vcc supply. Disconnect.
