Pin Description

Pin Number

Pin Name

Pin Function

1

OUT

Output pin and overvoltage protection (Output): Connect to the output ca-

pacitor and LEDs.

2

VIN

Supply (Input): Input voltage.

3

EN

Enable (Input): Logic high enables regulator. Logic low shuts down regula-

tor.

5

NC

No connect (no internal connection to die).

6

FB

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.

7

SW

Switch node (Input): Internal power transistor collector.

4,8

GND

Ground (Return): Ground.

EP

GND

Ground (Return): Exposed backside pad.
