Original Abstract Submitted
A switching power supply device includes an on-timing generation circuit that generates an on-timing signal for turning on a switching element. The on-timing generation circuit includes: an error amplifier that outputs an error amplification signal obtained by amplifying a difference between a feedback voltage and a reference voltage; a common voltage generation unit that generates a common voltage; a ripple signal generation unit that generates a forward phase ripple signal and a reverse phase ripple signal; and a comparator that generates the on-timing signal by comparing a pair of differential signals generated based on the error amplification signal, the common voltage, the forward phase ripple signal and the reverse phase ripple signal.
