A 60V Input Integrated 3-to-1 Dual Inductor Hybrid Dickson Converter

Abstract

This paper presents a design of dual inductor hybrid (DIH) converter based on a 3-to-1 hybrid Dickson converter with fully on-chip control system and power switches for high-input-voltage and high-conversion-ratio applications. Using a 180-nm high-voltage CMOS technology, the converter reaches ~93% peak efficiency at 6W output power and an output range from 3.3V to 9V for an input range from 48V to 60V.
