Abstract
A multi-phase switching converter includes: first and second sub-switching converters; switching signals operating first and second capacitors of the first and second sub-switching converters to respectively perform a switched capacitor switching on a first voltage between plural electrical connection states, to respectively switch a first and second switching nodes between a first and second divided voltages of the first voltage obtained from the switched capacitor switching and a first and second reference voltage potentials thereby performing the power conversion between a first and second power nodes. Each of a first and second switch circuits of the first and second sub-switching converters has corresponding plural first and second switches and corresponding first and second subsidiary switch. Each of the first and second subsidiary switch is coupled between the first and second capacitors and the first and second switching nodes, to respectively decide whether the first and second capacitor is electrically connected to a first and second inductor according to the switching signal corresponding to the first and second subsidiary switch, respectively.
