Pin Descriptions

Pin

NAME

FUNCTION

1

VCC

Power Supply to IC, a small bypass capacitor (0.1

F) to GND and closed IC

as possible.

2

GND

Ground. This pin should be tied as close to the ground output terminal of the

converter as possible to minimize load current effect on the voltage

regulation set point

3

OUT

Open-Collector Output .this pin is connected opto-coupler with the limit

resistor to error signal to the primary side.

4

ISEN

Current sense pin. The inverting input of the current loop op amp. This pin is

tied to the end of the current sense resistor through a decoupling resistor

and the threshold voltage at maximum current is 200mV.

5

VSEN

Voltage sense pin. Inverting input of the internal OP-amp. It connected to

the mid-point of a resistor divider that senses the output voltage.

6

DCDIM

In Analog dimming control, this pin is DC level signal input for brightness. If

the devise is PWM Dimming control, this pin adds a 0.1~1uF MLCC

capacitor to filtering PWM signal.

7

ADIM

Signal input for brightness control at PWM Dimming. When devise is in

analog dimming mode, this pin connects to GND.

8

VREF

Internal linear regulator output pin with an external ceramic capacitor of

1~2.2

F.
