Abstract
A multiphase charging circuit includes a first phase having a first switch and a second phase having a second switch to provide a system voltage for a system load, a control method of the multiphase charging circuit includes: generating a plurality of feedback control signals with generating each of feedback control signal based on a corresponding feedback signal, a ramp signal, a corresponding reference signal and a current flowing through the first phase; selecting one of the plurality of feedback control signals as a first enable signal; generating a first control signal of the first switch based on the first enable signal and a first time period control signal; generating a second enable signal by shifting a pre-determined phase difference to the first control signal; and generating a second control signal of the second switch based on the second enable signal and a second time period control signal.
