Abstract
A multi-phase signal control circuit includes: a comparator, configured to compare a triangular wave signal with a feedback control signal to output a first pulse width modulation signal, where the feedback control signal is a signal fed back by the power stage circuit; a phase switch circuit, configured to receive a phase switch signal and the first pulse width modulation signal to generate a first phase signal and a second phase signal, where the first phase signal and the second phase signal are used to control the power stage circuit to generate an output voltage signal.
