Multi-phase converter
An apparatus that includes first and second parallel converter branches, each parallel converter branch including an input node, N output nodes, a plurality of switches, a converter output node, and control logic. The control logic generates a first set of switch signals to control the switches of the first parallel converter branch and a second set of switch signals to control the second parallel converter branch, the first set switch signals and the second set of switch signals having respective duty cycles to cause each of the first and second parallel converter branches to output the DC output voltage on each of the N output nodes.
