Abstract
A converter can include: (i) a first switch having a first terminal for receiving an input voltage, and a second terminal coupled to a first terminal of a second switch; (ii) an inductor having a first terminal coupled to a common node of the first and second switches, and a second terminal coupled to a first terminal of a third switch, where second terminals of the second and third switches are coupled to ground; and (iii) a plurality of output channels coupled to a common node of the inductor and the third switch, where the converter operates in a buck-boost mode, a buck mode, or a boost mode based on the relationship between the input voltage and output voltages of the plurality of output channels.
