PIN 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
Power Supply Input. Must be closely decoupled to GND with a 10µF or greater
ceramic capacitor.
5
FB
Feedback Input. An internal resistive divider divides the output voltage down for
comparison to the internal reference voltage.
