Claim Text:
1. A method for controlling a multiphase interleaving converter, the converter including a plurality of phases, each of the plurality of phases including a high side switch and a low side switch, the method comprising: detecting a change of a load applied to an output terminal of the converter and providing a detection signal in response to detecting the change of the load; controlling a switch based on the detection signal, the switch having an output terminal coupled to an oscillator and configured to provide a first control signal; receiving the first control signal at an input terminal of an output comparator that includes an output terminal; generating, at the output terminal of the output comparator, a turn-off control signal for the high side and low side switches of all the phases of the converter; in response to the turn-off control signal, simultaneously turning off the high side and low side switches of all of the phases of the converter; and recovering a driving interleaving phase shift so as to restart a normal operation of the converter, wherein the switch comprises a transistor coupled between a first voltage reference and the oscillator.
