Power converter having multi-phase output stage and operating method thereof
A power converter including a multi-phase output stage, a comparator, and a time calculating unit is disclosed. The multi-phase output stage includes a plurality of channels. The comparator compares a first input signal with a second input signal to provide a setting signal. The time calculating unit adjusts on time duty cycles of the channels with the variation of the load according to the setting signal. When the load becomes larger, the frequency that the comparator provides the setting signal will be increased to cause that the on time duty cycles of the channels are overlapped.
