Department of Electronics and Electrical Engineering Graduate School Dankook University ABSTRACT
Recently, the importance for power management IC(PMIC) is emphasized as battery-powered portable electronics such as smartphone are commonly used.In addition,research and development on high efficiency isessential to maximize the use of portable devices that are preferred various functions than in the past.PMIC for high efficiency usually change drastically from Linear regulators to Switching regulators. But the switching regulators have disadvantage of low efficiency compared with linear regulatorat light load conditions. Therefore,this paper is presented the using of linear regulator to increase efficiency at light load conditions and the using of switching regulator at heavy load conditions.
