Abstract :
We report here a study on 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 core is used as the filter inductor in the buck converter. A 0.6-1.2W prototype system in package (SiP) buck converter is designed to operate at frequencies up to 10MHz.
