Abstract :
In this study we report a monolithic buck converter power IC with on-chip ferrite core inductors. The power IC is designed and fabricated with a standard 0.18μm CMOS process. On-chip inductor with ferrite epoxy core is used as the filter inductor in the buck converter. A 5V/500mA prototype system in package (SiP) buck converter is designed to operate at frequencies up to 10MHz.
