Description
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.
Ground.
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 (Adjustable Version) : Feedback Input Pin. Connect FB to the
center point of the external resistor divider. The feedback threshold
voltage is 0.6V.
