Description
Switch Pin. Connect inductor/diode here. Minimize trace area at this pin to reduce EMI.
GND pin
Feedback Pin. Reference voltage is 1.25V.
Regulator On/Off Control Input. A high input at EN turns on the converter, and a low input turns it off. When not
used, connect EN to the input source for automatic startup. The EN pin cannot be left floating.
Input Supply Pin. Must be locally decoupled - 4.7μF recommended to reduce input noise.
