Shutdown Input disables SMPS when low, but the voltage reference and low-battery com-
parator remain active.
Selects the main output voltage setting; 5V when low, 3.3V when high.
Feedback Input for adjustable output operation. Connect to an external voltage divider
between OUT and GND.
1.25V Reference Voltage Output. Bypass with 0.22μF to GND (0.1μF if there is no external
reference load). Maximum load capability is 250μA source, 20μA sink.
Low-Battery Output. An open-drain N-channel MOSFET sinks current when the voltage at
LBI drops below +1.25V.
Low-Battery Input. When the voltage on LBI drops below +1.25V, LBO sinks current.
Connect to V IN if not used.
Connect OUT to the regulator output. It provides bootstrapped power to both devices,
and also senses the output voltage for the MAX756.
Power Ground. Must be low impedance; solder directly to ground plane.
1A, 0.5 Ω N-Channel Power MOSFET Drain
