PIN DESCRIPTIONS

Pin

Name

Function

1

BOOST

Boost voltage that drives the internal NMOS control switch. A bootstrap capacitor is connected between the

BOOST and SW pins.

2

GND

Signal and Power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin

for accurate regulation.

3

FB

Feedback pin. Connect FB to the external resistor divider to set output voltage.

4

EN

5

Input supply voltage. Connect a bypass capacitor to this pin.

6

SW

Output switch. Connects to the inductor, catch diode, and bootstrap capacitor.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
