Hi,
We have designed PFC using L6562 referring application note AN2761 on that the auxiliary winding is used only to sense the zero current detect calc. is in Equation 65 but we also need to power the ic using the same winding can i get calculation that.
now for the testing purpose we powered the ic from the external source and we are not getting pulses (square waveform) at the gate pin its gives spikes. what could be the reason?
