2.3 Power Connection
Connect the power supply to VBAT and PGND. Set the power supply to 2 V, 100 mA
and measure the voltage on VMCU (TP27) to ensure it is operating at the voltage option selected by S1:
•
1.5 V
•
1.8 V
•
2.5 V
•
3.3 V
Measure the voltage on VBST to ensure it is either 3 V, 4 V, or 5 V. See
initial VMCU and VBST voltage.

Peak current drawn from the supply is 600 mA for boost converter operation. If device does not power up with 100 mA current limit,
increase the power supply current limit to 600 mA.
