Abstract
A multi-phase power converter and a method for balancing a plurality of currents in the multi-phase power converter. The multi-phase power converter has a pulse width modulation circuit, a current ordering circuit, and a plurality of currents, wherein each current of the plurality of currents has an associated phase. The converter determines the phase associated with one or more currents of a plurality of currents and whether a phase associated with one or more currents of the plurality of currents is active. The current levels of the plurality of currents are determined and a phase associated with a current having one of a lowest current level or a highest current level is activated.
