  • DC-DC converter
    Patent number: 10211730
    Abstract: A DC-DC converter 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.
