Abstract
A method for controlling an output of a power converter with a control circuit includes generating a drive signal to control switching of a switch to regulate the output of the power converter. It is detected if a switching period of one switching cycle of the drive signal exceeds a threshold switching period. The drive signal is disabled when a period of a switching cycle of the drive signal exceeds the threshold switching period for a threshold consecutive number of switching cycles.
