FUNCTION
Battery-Power Input
Power-Fail Input. When the voltage at PFI is below 614mV, PFO sinks current.
Open-Drain Power-Fail Output. PFO sinks current when PFI is below 614mV.
Active-Low Shutdown. Connect SHDN to BATT for normal operation.
Dual-Mode Feedback Input. Connect FB to GND for fixed-output operation (3.3V). Connect FB to a feed-
back-resistor network for adjustable output voltage operation (2V to 5.5V). FB regulates to 1.23V.
Ground
N-Channel MOSFET Switch Drain and P-Channel Synchronous-Rectifier Drain
Power Output and IC Power Input (bootstrapped). OUT is the feedback input for 3.3V operation. Connect
the filter capacitor close to OUT.
