Pin Definitions

Pin #

Name

Description

1

CS

Current Sense. This pin connects a current sense resistor to sense the MOSFET current for

peak-current-mode control in CV mode and provides for output-current regulation in CC mode.

2

GND

Ground.

3

COMI

Constant Current Loop Compensation. This pin connects a capacitor and a resistor between

COMI and GND for compensation current loop gain.

4

COMV

Constant Voltage Loop Compensation. This pin connects a capacitor and a resistor between

COMV and GND for compensation voltage loop gain.

5

VS

Voltage Sense. This pin detects the output voltage information and discharge time base on

voltage of auxiliary winding. This pin connected two divider resistors and one capacitor.

6

VDD

Supply. The power supply pin. IC operating current and MOSFET driving current are supplied

threshold voltages for startup and turn-off are 16V and 5V, respectively. The operating current

is lower than 5mA.

7

NC

No connection.

8

DRAIN

Drain. This pin is the high-voltage power MOSFET drain.
