The controller ground.
Hooking an optocoupler collector to this pin will allow regulation.
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.
This pin monitors the primary peak current but also offers a means to
introduce ramp compensation.
This pin is connected to an external auxiliary voltage and supplies the
controller.
The driver’s output to an external MOSFET gate.
