Abstract:
One embodiment of the invention includes a power regulation system. The system comprises a power regulator configured to periodically generate a switch signal that regulates a current flow through an inductor to set a magnitude of an output voltage. The system further comprises an overvoltage protection circuit configured to monitor a peak voltage magnitude of the switch signal and to generate an overvoltage indication signal in response to the peak voltage magnitude of the switch signal exceeding a predetermined limit.
