Abstract
The present disclosure relates to a switching power supply, and a control circuit and a control method of the switching power supply. The switching power supply comprises N-phase power conversion circuits, N being an integer greater than or equal to 1. The control circuit comprises a current reference signal generating means and a control means. The current reference signal generating means is configured to obtain an integration signal by integrating an error between a first compensation signal and a first voltage signal, and obtains a current reference signal by adding the integration signal and the first compensation signal. The control means provides control signals for respective ones of the N-phase power conversion circuits in accordance with the current reference signal. The first compensation signal represents a difference information between an output feedback signal of the switching power supply and a predetermined reference voltage.
