开关电源IC的绿色设计

Green Design of Switch Mode Power Supplies IC

由于对电器及电子产品的环保要求越来越高,迫使人们不得不思考如何规划产品“绿化”工程及打造绿色产业链等问题,而绿色设计是绿色产业链中重要和首要的环节。文中就绿色产业链的主要组成环节及开关电源IC绿色设计应该解决的主要问题及其必要性进行了讨论,提出低待机功耗、功率因数校正(PFC)、电磁兼容(EMC)及强大的保护等功能已成为全球半导体业界共同关注的课题,并提出了与用户紧密结合,在系统层面上进行绿色设计的重要性。

Because of the environmental protection request of the electric appliances and the electronics products become more and more high, we have to consider how to programing ＂green＂ engineering of product and create a green industry chain and so on ,the importance and firstest tache of green industry chain is green design. In this paper, we discuss the mainly tache of green industry chain, and carry on a discussion about the problem which should be resolved in the switch power supply IC green design and its necessity. Put forward many topics that the global semi-conductor industries pay attention to together,including power dissipation in standby mode, PFC, EMC and powerful protection. And put forward the close combine with user ,the importance of green design on system level.
