Pin Descriptions

NAME

FUNCTION

VCC

DRV

GND

Power source VCC pin.

Gate drive output to drive the external MOSFET.

Ground.

Current Sense pin. Connect with an external current sensing resistor to GND. CS

pin voltage is used to provide current feedback in the control loop and detect an

overcurrent condition.

COMP

OVP

DIM

LED output current feedback through a current sense resistor.

It’s a compensation of the error amplifier

Over-voltage protection.

FB Dimming Input. (Input PWM signal.)
