DAP018B - PWM Current-Mode Controller
A resistive divider from the auxiliary winding to this pin sets the OPP compensation level.
This pin offers an over *voltage protection input.
Wiring a capacitor to ground helps selecting the timer duration.
This pin offers a way to adjust the frequency modulation pace.
By connecting a resist

DAP018B Features
* the device takes advantage of the auxiliary winding negative swing to let the user adjust the maximum power the converter can deliver in high line conditions (OPP). When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatically freezes the peak cu
