Abstract
An over voltage protection circuit for single phase and multiphase buck converters. According to one embodiment, upon the occurrence of an over voltage condition, the high side switch is turned Off and the low side switch is On. As the output voltage drops below a lower threshold, the low side switch is turned Off thereby reducing or eliminating negative spikes on the voltage output.
