Pin Name
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): 2.7V to 8V for internal circuitry.
Output Pin and Overvoltage Protection (Output): Connect to the
output capacitor and LEDs.
Analog ground.
Power ground.
No connect (no internal connection to die).
Ground (Return): Exposed backside pad.
