Pin Name
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.
Analog ground.
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.
Power ground.
Ground (Return): Exposed backside pad.
