Abstract
A method comprises generating a first ramp signal and a second ramp signal for controlling a buck converter portion and a boost converter portion of a buck-boost converter respectively, comparing the first ramp signal and the second ramp signal to a control signal, controlling the buck converter portion using the comparing the first ramp signal to the control signal and the boost converter portion using the comparing the second ramp signal to the control signal, comparing a current flowing through the inductor to a current threshold and terminating a switching cycle based upon the comparing the current flowing through the inductor to the current threshold.
