Pin Function
Switch node (Output): Internal power BIPOLAR collector.
Ground (Return): Ground.
Feedback (Input): Output voltage sense node. Connect the cathode of the
LED to this pin. Connect current set resistor from this pin to ground.
Enable (Input): Logic high ( 1.5V) enables regulator. Logic low ( 0.4V) shuts
down regulator.
Supply (Input): Input Voltage.
Overvoltage protection (Input): Connect to the output to clamp the maximum
output voltage.
Analog ground. Internally connected to ground.
Power ground.
No connect (no internal connection to die).
Ground (Return): Exposed backside pad.
