چکیده

Abstract -This paper presents an optimum design for low-voltage, low-power DC-DC converter which has a controller and integrated CMOS switches using small size inductor (luH). Optimum design for single chip DC/DC converter is achieved by analyzing the amount of conduction and switching losses. Through the loss analyses, it is turned out that a constant frequency hard switching PWM converter with synchronous rectifier is most suitable among the several kinds of DC-DC converters for low voltage and low power applications.

A Buck-Boost Hybrid DC-DC Converter for Wearable Health Monitoring Devices

A hybrid approach of the DC-DC conversion is presented for battery-operated portable electronics systems such as wearable health monitoring devices. A switched-capacitor (SC) DC-DC converter is steered by hysteretic control to provide buck-boost conversion with a flexible conversion ratio, and its output is regulated by a low-drop-out (LDO) regulator delivering a low-ripple DC output. The SC DC...
