Pin Name

Description

1

BS

Internal Power NMOS Gate Drive Boost Input.

A 10nF or greater value capacitor should be connected from SW to BS for additional

Power NMOS gate driving purposes.

2

VIN

Power supply input.

The input supply pin for the device, VIN, is connected to a supply voltage between

4.75V to 24V.

3

SW

Power switching output.

The internal power MOS drain is connected to the inductor diode and VIN.

4

GND

Ground.

Device ground voltage reference.

5

FB

Feedback pin.

The feedback pin is connected to an external resistor divider to measure the output

voltage.

6

COMP

Error Amplifier Output.

Used for compensation of the regulation control loop. Connect a series RC network

from COMP to GND to compensate the regulation control loop and the COMP pin

value is 0.92V.

7

EN

Enable Input and dimming control.

This pin is set high to turn on the regulator and low to turn it off. The pin should be left

unconnected if not used.

8

NC

Not used

Exposed Pad

GND

Ground.

Device ground voltage reference.
