Pin Function
Output Pin and Overvoltage Protection (Output): Connect to the output
capacitor and LEDs
Supply (Input): Input voltage.
Enable (Input): Logic high enables regulator, logic low shuts down regulator.
No connect (no internal connection to die).
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.
Switch Node (Input): Internal power transistor collector.
Ground (Return): Ground.
Ground (Return): Backside pad.
