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.
