Abstract
The present invention provides a buck-boost converter including a converter power stage, a first mode control unit, and a second mode control unit. In the buck-boost converter, the converter power stage may include at least one inductor and a plurality of switching devices. Further, the first mode control unit may operate the converter power stage in a buck mode and regulate an output voltage of the converter power stage as a first voltage. Further, the second mode control unit may operate the converter power stage in a boost mode or a buck-boost mode, and regulate an output voltage of the converter power stage as a second voltage higher than the first voltage.
