Lzc8650c Ic Datasheet Pdf -
The VCC pin gets its initial startup current through high-value startup resistors. Once the MOSFET starts switching, the auxiliary winding of the flyback transformer takes over and delivers steady power to VCC. The ZCD pin monitors the auxiliary winding waveform to precisely timed turn-on moments, minimizing switching stress. Finding the LZC8650C Datasheet PDF
