Abstract
A control method of multi-phase converters, wherein the multi-phase converter includes a plurality of switching circuits coupled in parallel between an input voltage and a load. The control method includes: comparing a feedback signal with a reference signal to generate a comparison signal, wherein the feedback signal is indicative of an output voltage provided to the load; determining the number of switching circuits for power operation based on the load current; detecting a period of the comparison signal; comparing the detected period of the comparison signal with a time threshold to determine whether a transient rise of load current has occurred; and getting all the switching circuits into power operation if a transient rise of load current is detected.
