Pin Descriptions

Pin

NAME

FUNCTION

1

VIN

Power Supply for the device. Internal Zener Clamp for wide range

LED light bar voltage. Connecting a RIN to LED anode for current

limit and a capacitor

to GND for filter out noise

2

GND

Ground

3

REF

LED Reference Voltage,

It’s essential to connect REF pin with a

SMD ceramic capacitor to filter the 100/120Hz ripple.

4

OCP

LED current feedback and maximum LED current limit.

5

OUT

This pin connects the MOSFET gate to regulate LED current ripple.

6

OVP

Over voltage Protection for Short LED protection
