European Input Voltage Range to 24V@2.5A Primary Side Regulated Isolated Flyback Reference Design

A quasi-resonant primary-side regulated isolated Flyback is used to provide 24V industrial voltage at 1.9A average (2.5Apeak) on secondary side and 24V @ 300mA on primary side from an AC input voltage of 170Vac-264Vac. The converter does not employ any optocoupler and regulates both output voltages (...)
