Abstract: A method of operating a buck-boost converter including an inductor and a capacitor includes; operating the buck-boost converter in boost mode until a level of an input voltage applied at an input node of the buck-boost converter reaches a desired level of an output voltage apparent at an output node of the buck-boost converter, and after the level of an input voltage reaches the desired level of the output voltage, operating the buck-boost converter in buck mode, wherein operating the buck-boost converter in buck mode and operating the buck-boost converter in boost mode overlap at least in part temporally proximate a point at which the level of the input voltage exceeds the level of the output voltage.
