Abstract
Official abstract text for this publication.
In one embodiment, a control circuit configured for an interleaved switching power supply, can include: (i) a feedback compensation signal generation circuit configured to sample an output voltage of the interleaved switching power supply, and to generate a feedback compensation signal; (ii) a first switch control circuit configured to compare a first branch voltage signal that represents an inductor current of a first voltage regulation circuit against the feedback compensation signal, where when the first branch voltage signal is consistent with the feedback compensation signal, a first switch on signal is generated to control a first main power switch of the first voltage regulation circuit to be on for a predetermined time, and then off; and (iii) a second switch control circuit configured to compare a second branch voltage signal that represents an inductor current of a second voltage regulation circuit against the feedback compensation signal.
