摘要

在本研究中，我们报导了一种带有片上铁氧体磁芯电感的单片降压转换器功率集成电路。该电源IC采用标准的0.18μm CMOS工艺设计和制造。降压变换器采用铁氧体环氧铁芯片上电感作为滤波电感。5V/500mA封装系统(SiP)降压转换器原型设计工作频率高达10MHz。

CMOS DC to DC switched converter with on chip inductors

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.
