Pin Description

Pin Number Pin Name Function

RI Set the bias current to determine the normal switching frequency

2 FB

Voltage feedback pin. By connecting an opto-coupler to close the

control loop, it can achieve the system regulation

3 SENSE Current sense pin. Connect it to sense the MOSFET current

4 GND Ground

5 GATE Gate drive output to drive the external MOSFET

6 VCC Supply voltage pin

7 HV

Connect this pin to positive terminal of bulk capacitor to provide the

startup current for the controller. When VCC voltage reachs UVLO

(on), this HV loop will be turned off to save the power loss of the

startup circuit
