次级同步整流及输出均流的集成控制器

Integrated Controller of Secondary Synchronous Rectification and Current Share

Compact PCI(简称 cPCI)电源在计算机、工业和电信领域的应用已经得到了认可。cPCI 电源采用了标准的工业机械结构和高性能连接技术。然而,一般的 cPCI 电源沿用的是传统的二极管整流技术,应用时会造成很大的功率损耗,并且限制了可用输出功率。详细介绍了一种采用同步整流技术的 cPCI 电源,它利用独特的次级同步整流和带有输出电流均流功能的集成控制器 SC4910,使之在效率和性能方面部有了很大的提高。

A conventional cPCI rises traditional diode rectification technology,resulting high power loss and limited output power available for system application.The advantage of a cPCI power supply with synchronous rectification technology and current share using a IC controller 5C4910 is introduced.Quantitative analysis shows that the cPCI power supply exhibits much higher efficiency and improved performance.
