Pin Descriptions

Pin Number

Pin Name

Function

BNO

Brownout Protection Pin. Connected to GND by a resistor to set the brownout level. This pin is

shortened to the ground to set the maximum brownout voltage

Voltage Feedback Pin., Connecting it with an opto-coupler to close the control loop can

achieve system regulation

SENSE

Current Sense Pin. Connect it to sense the MOSFET current

GND

Ground

GATE

Gate drive output to drive the external MOSFET

VCC

Supply Voltage Pin

Connect this pin to the positive terminal of bulk capacitor to provide start-up current for the

controller. When VCC voltage reaches UVLO (on), this HV loop will be turned off to save the

power loss of the start-up circuit
