Abstract
A flyback converter is disclosed that times a detection time for each cycle of a power switch transistor. The detection time ends when a sense resistor voltage exceeds a threshold voltage. Over a half cycle of an AC input voltage to the flyback converter measures a series of detection time and determines a minimum detection time from the series of detection times. If the minimum detection time exceeds a brownout delay, a brownout condition exists. If the minimum detection time is less than an overvoltage delay, an overvoltage condition exists.
