Abstract
A switching converter includes: a power stage circuit including at least one switch to switch an inductor to convert an input power to an output power; a modulation circuit executing a pulse width modulation according to a feedback signal related to the output power and a reference signal to generate a modulation trigger signal; a time calculation circuit generating a pulse width modulation (PWM) signal according to the modulation trigger signal to control the at least one switch and computing an ON-time or an OFF-time of the PWM signal; and a time adjustment circuit generating a time adjustment signal according to a first clock signal related to the PWM signal, wherein the time adjustment signal adjusts the ON-time or OFF-time in a random or a pseudo-random fashion, so as to suppress a noise resulting from a switching frequency of the PWM signal.
