Abstract: In a DC/DC converter, a driving method thereof, and a power supply using the same, the DC/DC converter includes a plurality of power switches connected as a serial string between an input terminal and a ground terminal, a first capacitor connected to at least two power switches of the serial string in parallel, an inductor connected between an intermediate node of the serial string and an output terminal, a second capacitor connected between the output terminal and the ground terminal, and a plurality of drivers configured to generate a switching control signal for each of the plurality of power switches. A voltage having no correlation with a voltage of the input terminal is supplied to a power terminal of each of the plurality of drivers.
