Abstract
A switching power converter includes: a power stage circuit for converting an input voltage to an output voltage by switching an inductor with a synchronous or an asynchronous mode; an error amplifier to generate an error amplified signal; a modulation comparator for generating a primary modulation signal by comparing the error amplified signal and a ramp signal; a pulse skipping comparator for generating a pulse skipping control signal by comparing the error amplified signal and a skipping reference signal; and a switching control unit for masking the primary modulation signal by the pulse skipping control signal. During the synchronous mode, the skipping reference signal has a predetermined reference level. When the synchronous mode is changed to the asynchronous mode, the skipping reference signal turns to the predetermined reference level superposing a compensation reference level, and subsequently the skipping reference signal gradually returns to the predetermined reference level.
