Abstract: Phase reassignment among power converters is disclosed. Multi-phase power converters of a plurality are arranged such that the various phases of each can be shared. When a given power converter has a high demand current and a phase of another power converter in the same group is currently unused, that phase may be borrowed by the given power converter to meet the demand current. The power converter that borrows a phase from another power converter is designated as the leader, while the borrowed phase is designated as a follower. The regulated supply voltage is determined by the leader power converter, irrespective of the regulated output voltage to be generated by the power converter from which another phase is borrowed.
