A quasi-resonant primary-side regulated isolated Flyback is used to provide 12V @ 500mA from universal input voltage (90Vac to 265Vac). The converter does not employ any optocoupler and regulates the output voltage by sensing the auxiliary winding on primary side. A peak input voltage detector is (...)
