Abstract

See full text

A control circuit for a switching converter, can include: a ripple signal generation circuit configured to generate a ripple signal with a same frequency and phase as an inductor current of the switching converter, where the ripple signal changes between zero and a preset value; a superimposing circuit configured to superimpose the ripple signal on a feedback signal representing an output voltage of the switching converter, in order to generate a loop control signal; and a switching control signal generation circuit configured to generate switching control signals according to the loop control signal and a reference signal, in order to control a switching state of a power stage circuit in the switching converter.
