Typical Application Example Pin N 5 Pin Name Function Pin Description 1 GND − The controller ground. 2 FB Feedback pin Hooking an optocoupler collector to this pin will allow regulation. 3 OPP/OVP Adjust the Over Power Protection Latches off the part A resistive divider from the auxiliary winding to this pin sets the OPP compensation level. When brought above 3 V, the part is fully latched off. 4 CS Current sense + ramp compensation This pin monitors the primary peak current but also offers a means to introduce ramp compensation. 5 VCC Supplies the controller This pin is connected to an external auxiliary voltage and supplies the controller. When the VCC exceeds a certain level, the part permanently latches off. 6 DRV Driver output The driver’s output to an external MOSFET gate.
