Pin #

Name

Description

1

CS

Current Sense

. This pin connects a current-sense resistor, to detect the MOSFET current for

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

2

VDD

Power Supply

. IC operating current and MOSFET driving current are supplied using this pin.

startup and turn-off are 16V and 5V, respectively. The operating current is lower than 5mA.

3

GND

Ground

4

COMR

Cable Compensation

. This pin connects a 1µF capacitor between the COMR and GND pins

for compensation voltage drop due to output cable loss in CV mode.

5

VS

Voltage Sense

. This pin detects the output voltage information and discharge time based on

voltage of auxiliary winding.

7

HV

High Voltage

. This pin connects to bulk capacitor for high-voltage startup.

8

DRAIN

Driver Output

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