Abstract

A buck-boost converter includes a voltage input terminal, a voltage output terminal, a first switch, a second switch, an inductor, a third switch, and an auxiliary capacitor. The first switch includes a first terminal coupled to the voltage input terminal, and a second terminal. The second switch includes a first terminal coupled to the voltage output terminal, and a second terminal. The inductor is coupled between the second terminal of the first switch and the second terminal of the second switch. The third switch includes a first terminal coupled to the second terminal of the second switch, and a second terminal. The auxiliary capacitor is coupled to the second terminal of the third switch.
