Abstract
A quick response mechanism for a switching power system includes a detector and an adjustor connected to the detector. The detector is configured to directly monitor the drop of the output voltage of the switching power system so that a quick response could be immediately triggered when a load transient occurs. The adjustor is configured to adjust the duration of the quick response, thereby preventing the output voltage from undershoot or ringback.
