摘要
通过对高可靠混合集成DC/DC变换器小型化难点分析,阐述了在兆赫兹开关频率下,采用LTCC工艺实现平面变压器的原理。并从设计、版图、工艺三方面采取措施,制作了一种基于LTCC工艺的兆赫兹级变压器,并通过工程实例进行了验证。
The problems of miniaturization of high reliable DC/DC converter based on hybrid IC process were analyzed.The mechanism of realizing plane transformer by LTCC process combined with megahertz switching frequency in high reliability DC/DC converter was expounded.By making a comprehensive consideration of design,layout and process,a megahertz transformer base on LTCC process was designed and implemented,and it was verified by an engineering example.
