PIN FUNCTIONS

Pin #

Name

Description

1

RS

LED current sense input. Connect a current-sense resistor to program the LED

average current to IN.

2

GND

Ground.

3 ,7

NC

Not connected.

4

EN/DIM

Enable/dimming command input. For PWM dimming, apply a square wave signal to

EN/DIM. For analog dimming, apply a 0.3V to 2.5V DC voltage to control the LED

current range linearly from 25% to 200%. Turn off the output current when pulling

5, 6

SW

Drain of internal MOSFET. Connect the inductor common terminal and Schottky anode

to SW.

8

IN

Input supply. Connect an appropriate decoupling capacitor from IN to GND.
