NAME

FUNCTION

1

SW

Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the

power inductor and output rectifier to SW. SW can swing between GND and 28V.

2

GND

Ground Pin

3

FB

Feedback Input. The FB voltage is 0.6V. Connect a resistor divider to FB.

4

EN

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 supply for automatic

startup.

5

IN

Input Supply Pin. Must be locally bypassed.
