基于磁粉芯的小型化磁耦合VRM设计
Design of Miniaturized Magnetic Coupled VRM Based on Magnetic Powder Core
摘要
Abstract
In response to the large volume problem of the traditional voltage regulation modules(VRM)coupling inductance using ferrite magnetic cores,the magnetic powder cores with higher saturation magnetic density are used as the magnetic core materials to reduce the volume of magnetic components.The design scheme and process for VRM coupling inductance based on magnetic particle cores are proposed.Finally,based on the design parameters,a magnetic coupled VRM prototype is built.The current density of the prototype module reached 0.5 A/mm2,the total height of the inductor is only 5 mm,and the performance is good.The proposed scheme and design process are verified to be correct and effective through the practical examples.The miniaturization and low cross-section of VRM coupled inductors can be achieved.关键词
