  • Publication number: 20230046982
    Abstract: In a switching power supply device, a comparison voltage is generated based on a feedback voltage commensurate with the output voltage. Synchronously with the output transistor being turned on, a ramp voltage is made to start increasing from a first initial voltage; when the ramp voltage exceeds the comparison voltage, the output transistor is turned off. When the switching frequency is lowered from a first frequency to a second frequency, it is switched to the second frequency after the lapse of a transition period. During the transition period, the ramp voltage is made to start increasing from a second initial voltage (>first initial voltage).
