Pin Function

1

IN

Input: +2.5V to +14V supply for internal circuity.

2

GND

Ground: Return for internal circuitry and internal MOSFET (switch) source.

3

SW

Switch Node (Input): Internal MOSFET drain; 22V maximum.

4

FB

Feedback (Input): Output voltage sense node. Compared to V

input voltage.

5

VC

Control (Input): Output voltage control signal input. Input voltage of 0.8V to

3.6V is proportional to 4.8V to 22V output voltage (gain of 6). If the pin is not

connected, the output voltage will be V
