P Ground
I
Step-Up Regulator Feedback Input. Connect a sense resistor from FB to
ground.
Enable and Dimming Control Input. LED brightness and IC shutdown are
I controlled by the voltage on EN. Driving low for longer than 4ms to
shutdown the IC.
I Over-voltage protection input. Connect to the output.
