Abstract

The push for logic levels of one volt and below creates a need for the development of new power electronic circuits. Today's power electronic circuits can only hope to meet an efficiency of 50% for tomorrow's logic needs. Currently, a DC-DC power converter supply is placed adjacent to every Pentium/sup TM/ processor on every motherboard in order to meet the processor power and regulation requirements. The Intel spec for this DC-DC converter is known as the VRM (Voltage Regulator Module). Entire industries have been formed to meet this need for present motherboards and special power consortiums are forming to meet tomorrow's needs. This has resulted in an explosion of new control ICs and MOSFETs from companies such as Motorola, Harris, TI, Fairchild, National, Linear Technology, Maxim, and International Rectifier. The paper addresses the transistor's role in power needs for present and future logic levels. The subject matter includes powering Pentium processors for desktop PCs (5 VDC to 3.3 VDC converters) as well as the Merced/sup TM/ mainframe processor needs (48 to 3.3 VDC) to the several hundred amp logic levels of tomorrow's mainframes. Included are references to design kits, Websites, and SPICE models for some of these power converters.

晶体管模式的转变需要满足微处理器的功率需求

对1伏及以下逻辑电平的推动产生了开发新的电力电子电路的需求。今天的电力电子电路只能希望达到50%的效率，以满足明天的逻辑需求。目前，为了满足处理器的功率和调节要求，每个主板上的每个Pentium/sup TM/处理器附近都放置了一个DC-DC电源转换器。这种DC-DC转换器的英特尔规格被称为VRM(稳压模块)。整个行业已经形成，以满足当前主板的这种需求，特殊电源联盟正在形成，以满足明天的需求。这导致了摩托罗拉，哈里斯，TI, Fairchild, National, Linear Technology, Maxim和国际整流器等公司的新型控制ic和mosfet的爆炸式增长。本文讨论了晶体管在当前和未来逻辑级的功率需求中的作用。该主题包括为台式电脑的奔腾处理器(5 VDC至3.3 VDC转换器)以及Merced/sup TM/大型机处理器需求(48至3.3 VDC)供电，以达到未来大型机的数百安培逻辑电平。其中包括一些电源转换器的设计套件，网站和SPICE模型的参考资料。
