Beschreibung
Zusammenfassung:	A power controller includes an inductor coupled to an input terminal to which an input voltage is input, a first switch coupled between the inductor and a first power source voltage output terminal, a second switch coupled between the inductor and a ground, a switch controller controlling a voltage output to the first power source voltage output terminal by controlling duties of the first and second switches according to a feedback voltage input to a feedback terminal corresponding to a voltage output to the first power source voltage output terminal, and a diode coupled between the first power source voltage output terminal and the feedback terminal, and preventing a voltage of the first power source voltage output terminal from increasing higher than a breakdown voltage of the first and second switches.
