Pin Function
Switch Node (Input): Internal power bipolar collector.
Analog Ground (Return): Ground.
Power Ground (Return): Ground.
Feedback (Input): Output voltage sense node. Connect the cathode of the
LED to this pin. A resistor from this pin to ground sets the LED current.
Enable (Input): Logic high enables regulator. Logic low shuts down regu-
lator.
Supply (Input): 2.8V to 6.5V for internal circuitry.
Overvoltage Protection (Input): Connect to the output.
Not Connected
Exposed Backside Pad: Connect to ground.
