Connected to GND by a resistor to set the brownout level. This pin is shortened to the ground to set the maximum brownout voltage 2 FB Voltage Feedback Pin., C onnecting it with an opto-coupler to close the control loop can achieve 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

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 R10 5.1k C10 0.1F 4.7k 20k 2nF R12 620 0.5 7N60 BD1 100k VOUT J1 C2 100F U3 AZ431 FR107 510 20k 470F L2 5HD3 1000F T HV BNO GATEVCC FB GND U1 AP3107Z 22F SENSE 2kR11 0.1F 470pF MBR20H100C L1 J2 C11 D4R13
