High Efficiency DC-DC Buck Converter Architecture Suitable For Embedded Applications Using Switched Capacitor

Abstract

Here we look inside how the switched capacitor has evolved over the passage of years with special emphasis to the dc-dc buck converter.It also discusses why there is a strong potential to further the study related to designs based around a switched capacitor Buck Converter for embedded applications. The main objective of the paper is to look into the controller design for minimizing size, enhancing efficiency and reliability of power converters in portable electronic equipment such as mobile phones and PDAs.The converter is designed in 0.18- m CMOS process to get regulated 1.3–1.6 V output from 3.3 V input supply. The buck converter is designed by using simple block called as cross coupled converter.
