Pin
Name
Description
1
RUN
Run Control Input. Forcing this pin
above 1.5V enables the part.
Forcing this pin below 0.3V shuts
down the device. In shutdown, all
functions are disabled drawing
<1
μA supply current. Do not leave
RUN floating.
2
GND
Ground Pin.
3
SW
Switch Node Connection to
Inductor. This pin connects to the
drains of the internal main and
synchronous power MOSFET
switches.
4
VIN
Main Supply Pin. Must be closely
decoupled to GND, Pin 2, with a
2.2
μF or greater ceramic capacitor.
5
VFB
Feedback Pin. Receives the
feedback voltage from an external
resistive divider across the output.
5
VOUT
Output Voltage Feedback Pin. An
internal resistive divider divides the
output voltage down for comparison
to the internal reference voltage.
