ABSTRACT:
An operating frequency generating method and circuit for a switching voltage converter are provided. The method includes the following steps. First, a reference clock signal and a digital period signal are received. The phase of the digital period signal is delayed according to at least one different delay time, so as to generate at least one delay period signal. The digital period signal or one of the delay period signals is selected as an operating frequency of the switching voltage converter at every predetermined time interval.
