Abstract

Multiphase coupled inductor is a key technology for ripple reduction and fast transient in pulsewidth-modulated power converters. This letter presents the modeling and design of multiphase integrated planar symmetric (MIPS) coupled inductor, together with a hybrid-switched-capacitor dc-dc converter for ultrathin multiphase point-of-load voltage regulation modules. The benefits of MIPS inductors are quantified. A systematic approach to designing high-performance multiphase MIPS inductors is introduced and validated by a 10 V input, 1 V output, 10 A two-level four-phase coupled 3-MHz hybrid-switched-capacitor dc-dc converter with compact size and fast transient.
