Abstract
A multiphase switching converter having a plurality of switching circuits and a control circuit, the plurality of switching circuits provide an output voltage, the control circuit provides a plurality of switching control signals to turn ON the plurality of switching circuits successively based on the output voltage and a reference signal, when the output voltage is detected overshooting, the control circuit turns OFF a current switching circuit, and when the output voltage is detected recovering from overshooting, the control circuit turns ON the current switching circuit again for a first time period until a sum of the first time period and a second time period achieves a predetermined value, wherein the second time period is a time period the current switching circuit maintains ON uninterruptedly before the output voltage is detected overshooting.
