摘要
A flyback converter controller is provided with a single terminal through which the flyback converter controller senses for over-voltage faults for an input voltage and also senses for open circuit faults for an auxiliary winding. A first voltage divider provides a divided version of the input voltage to the single terminal. The controller compares a voltage for the single terminal to at least one over-voltage threshold to detect the over-voltage fault for the input voltage.
