Abstract
The paper describes an efficiency comparison between two VRM topologies, concretely the synchronous buck and the synchronous cascade-buck converters. The comparison is carried out among optimal designs. The comparison is made among designs that have the same size of the output filter or the same ripple values. The paper shows that synchronous cascade-buck converter is more efficient, although the current must go through two switches.
