Description
1
RUN
Regulator Enable control input. Drive RUN above 1.5V to turn on the part. Drive RUN
below 0.3V to turn it off. In shutdown, all functions are disabled drawing <1μA supply
current. Do not leave RUN floating.
Ground Pin.
2
GND
3
SW
Power Switch Output. It is the Switch note connection to Inductor. This pin connects to the
drains of the internal P-CH and N-CH MOSFET switches.
Supply Input Pin. Must be closely decoupled to GND, Pin 2, with a 2.2μF or greater ceramic
capacitor.
VFB (CM3706): Feedback Input Pin. Connect FB to the center point of the external resistor
divider. The feedback threshold voltage is 0.6V.
