On TOP227YN, Drain voltage goes upto 468VAC at 220V supply. what are the effects of high voltage and currents at input and output. How long does it take to break the device. Also Shunt regulator voltage is 6.73V at 5.05 mA Ic. what are the limits on voltages at 5.05 mA control pin Current.
We see the voltage on drain pin is continuously flickering and doesnot go to Zero at turn off is it normal ?
How can we make it stable?
