Abstract
A multi-phase switching converter comprising a plurality of switching circuits, a comparing circuit and a control circuit. The comparing circuit generates a comparison signal based on a reference signal and the output voltage of the multi-phase switching converter. The control circuit can turn on the following switching circuit based on the comparison signal only after the time from the current switching circuit being turned on reaches a first time threshold or the off-time of the current switching circuit reaches a second time threshold, wherein the first time threshold is longer than the second time threshold.
