  • Patent number: 11050345
    Abstract: A power supply apparatus that can realize ripple reduction, and an electronic control unit including the power supply apparatus are provided. In view of this, a PWM controller generates a PWM signal, and a PFM controller generates a PFM signal having a phase independent of the PWM signal. A level-fixed period generating circuit sets a level-fixed period having a start timing at a selection timing set to an edge of the PFM signal. A mode selecting circuit selects, at the selection timing and as a switching control signal, the PWM signal instead of the PFM signal, and controls a logic level of the switching control signal in the level-fixed period starting at the selection timing, such that the logic level becomes a fixed logic level.
