Pin Name

Description

SW

Switch Pin. Connect inductor/diode here. Minimize trace area at this pin to reduce EMI.

GND

GND pin.

FB

Feedback Pin. Reference voltage is 0.25V. Connect cathode of lowest LED and resister here.

EN

Converter On/Off Control Input. A high input at EN turn 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.

OVP

Output Voltage detect pin for over voltage protection.

Input Supply Pin. Must be locally bypassed with 1

μF or 2.2μF to reduce input noise.
