Function
Supply Input Pin. Must be closely decoupled to GND with a 2.2μF or
greater ceramic capacitor.
Power Switch Output. It is the switch node connection to external
inductor. This pin connects to the drains of the internal P-Channel
and N-Channel MOSFET switches.
Supply Input Pin. Must be closely decoupled to GND with a 2.2μF or
greater ceramic capacitor.
Power Switch Output. It is the switch node connection to external
inductor. This pin connects to the drains of the internal P-Channel
and N-Channel MOSFET switches.
Regulator Enable Control Input. Drive EN above 1.5V to turn on the
part. Drive EN below 0.3V to turn it off. In shutdown, all functions
are disabled drawing <1μA supply current. Do not leave EN floating.
Feedback Input Pin. Connect FB to the center point of the external
resistor
divider. The regulated voltage on this pin is 0.6V.
