Abstract
A multi-phase interleaved converter can include: (i) a plurality of phases, where each phase of the multi-phase interleaved converter includes a buck-type power stage having a power switch, a freewheeling switch and an inductor, a switching control circuit and a reference signal generator, and where each switching control circuit includes: (ii) an adder that receives a ramp signal and a feedback signal that represents an output voltage, and generates a feedback voltage signal; (iii) a comparator that receives the feedback voltage signal and a reference voltage signal, and generates a comparator output signal; and (iv) a logic circuit that receives the comparator output signal and an output from an on time control circuit, and controls a switching operation of the power switch.
