3 Enable Operation

The demo board includes a spot for a pullup resistor R5 (not stuffed) to enable the device once VIN has exceeded 1.8 V (typical). A typical value for this resistor is 100 KΩ. Otherwise, use the EN post to apply a logic signal to test start-up and shutdown of the device. Never allow the EN voltage to exceed VIN.
