Abstract: A DC-DC converter including an input, an output, a conversion circuit, and a switch control circuit. The input inputs input voltage. The output outputs output voltage. The conversion circuit a plurality of semiconductor switches, and converts the input voltage to the output voltage by switching operation of one or more semiconductor switches of the plurality of semiconductor switches. The switch control circuit selects one or more semiconductor switches performing the switching operation from the plurality of semiconductor switches based on the input voltage and a predetermined lookup table, and controls the switching operation of the one or more semiconductor switches.

Abstract: A DC-DC converter as embodiments of the present invention includes an input terminal, multiple output terminals, an inductor, a first switch, a first condenser, a second switch and a switch controller. One end of the inductor is connected to the input terminal. The first switch is subjected to on-off control to change a current flowing through the inductor. The first condenser has one end connected between the inductor and a first output terminal, which is one of the multiple output terminals, and has the other end connected to a ground. The second switch is connected between the inductor and the first condenser. The switch controller controls the second switch to turn on when the first switch is turned off while a first output voltage from the first output terminal is smaller than a predetermined first threshold value.
