Abstract
One embodiment of the invention includes a switching power supply system. The system includes a switch network comprising at least one switch configured to provide an output voltage based on switching activity thereof. The system also includes a switching controller configured to control the switch network to maintain the output voltage provided at an output based on a feedback signal associated with the output voltage. A converter pulse detector is configured to detect an output voltage overshoot condition based on the switching activity of the switch network corresponding to a transition in an output load to which the output voltage is provided.
