| Abstract: | 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. |
