Abstract
A method comprises detecting an input voltage and an output voltage of a buck-boost converter, wherein the buck-boost converter comprises a first high-side switch and a first low-side switch connected in series across an input capacitor, a second high-side switch and a second low-side switch connected in series across an output capacitor and an inductor coupled between a common node of the first high-side switch and the first low-side switch, and a common node of the second high-side switch and the second low-side switch and configuring the buck-boost converter such that at least one of the first high-side switch and second low-side switch operates at a fixed duty cycle mode.
