A novel integrated implementation of a high step-down multiphase buck for low voltage power supply is presented. The design and test chip measurements of a [10.8, 16]V to [0.65, 2]V, 2A, 10 MHz, 25.6 mW/mm2, four-phases single-chip solution are presented with considerations on architecture, passive components, problems related to high frequency integration and relative improvements on power density with respect to previous solutions.

Abstract
A novel integrated implementation of a high step-down multiphase buck for low voltage power supply is presented. The design and test chip measurements of a [10.8, 16]V to [0.65, 2]V, 2A, 10 MHz, 25.6 mW/mm2, four-phases single-chip solution are presented with considerations on architecture, passive components, problems related to high frequency integration and relative improvements on power density with respect to previous solutions.
