Abstract
A multi-phase switching converter, includes: plural sub-switching converters; and a control circuit. Plural switching signals operate a capacitor of one of the plural sub-switching converters and a capacitor of another one of the plural sub-switching converters, to conduct a switched capacitor switching on a first voltage, thus switching an inductor switching node in each sub-switching converter between a divided voltage of the first voltage and a reference potential and to thereby execute a power conversion between the first voltage and a second voltage. When the inductors of each of the plural sub-switching converters are coupled with one another in a non-electromagnetic fashion, the multi-phase switching converters operate in a non-resonant mode. When the inductors of at least two of the plural sub-switching converters are electromagnetically coupled with one another, the multi-phase switching converters operate in a resonant mode or in the non-resonant mode.
