Pin Function
Switch node (Input): Internal power BIPOLAR collector.
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 regulator.
Supply (Input): 2.5V to 10V for internal circuitry.
Overvoltage protection (Input): Connect to the output.
Analog ground.
Power ground.
No connect (no internal connection to die).
Ground (Return): Exposed backside pad.
