Abstract
An apparatus includes a buck-boost converter comprising a buck portion and a boost portion connected in cascade, and a controller comprising a first timer and a second timer, wherein the first timer is configured to determine a turn-on time of a high-side switch of the buck portion, and wherein the first timer determines the turn-on time of the high-side switch of the buck portion based on a comparison between a first signal and a second signal, and wherein the first signal is proportional to an output voltage of the buck-boost converter and the second signal is generated based on a signal proportional to an input voltage of the buck-boost converter, and the second timer is configured to determine a turn-on time of a low-side switch of the boost portion.
