Abstract: A switching regulator includes a power converting unit and a switch driving unit. The power converting unit is configured to generate a direct current (DC) output voltage based on a switch driving signal and a DC input voltage. The switch driving unit is configured to generate a ripple voltage having information of an inductor current flowing through the power converting unit, add the ripple voltage to a reference voltage to generate a first voltage having a ripple, generate a feedback voltage based on the DC output voltage, compare the first voltage with the feedback voltage in a hysteresis mode to generate a comparison output, and generate the switch driving signal based on the comparison output.

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.
