Hysteretic Buck-Boost Converter for Wearable Applications

Abstract

This paper presents a novel Buck-Boost converter architecture targeting wearable applications, utilizing hysteretic control. The topology consists of three comparators, a derivative circuit, logic, timers and power switches. Macromodel level simulation results show < 5mV line and load regulation results, demonstrating that this topology promises to be a convenient solution for wearable platforms and other applications where good line regulation and low quiescent current are essential.
