NAME

FUNCTION

1

RUN

Chip Enable Pin. Drive RUN above 1.5V to turn on the part.

Drive

RUN below 0.3V to turn it off. Do not leave RUN floating.

2

GND

Ground Pin

3

SW

Power Switch Output. It is the switch node connection to Inductor.

This pin connects to the drains of the internal P-ch and N-ch MOSFET

switches.

4

VIN

or greater ceramic capacitor.

5

VOUT

Output Voltage Feedback Pin. An internal resistive divider divides the

output voltage down for comparison to the internal reference voltage.
