A buck-boost converter may include a first switch, an inductor, a first diode, a second switch, a second diode, and a capacitor. A cathode end of the first diode may be coupled to a first end of the inductor and a second end of the first switch. An anode end of the second diode may be coupled to a second end of the inductor and a first end of the second switch. A second end of the capacitor may be coupled to a second end of the second switch and an anode end of the first diode. A first end of the capacitor may be coupled to a cathode end of the second diode.
