  为推广高效率节能产品,越来越多的国家和地区纷纷发布了各种节能规范和标准。例如,国际能源署(IEA)所倡导“1W计划”,美国环保署(EPA)的“能源之星”计划,以及中国节能产品认证中心(CECP)所制定的规章等都把节能环保放在重要位置。如何提高电源的效率,是目前电源设计中面临的重要课题。数字电源技术的出现为提高电源的效率提供了新的方法。 ADP1043是ADI公司推出的一款针对高端服务器、存储器以及通信设备等电源所设计的数字电源控制器,可支持多种拓扑结构,并利用直观的图形用户界面(GUI)无需用语言进行编程,便可在几分钟之内配置包括频率、时序、电压设置与保护限制等系统电源参数。图1所示为ADP1043的典型应用电路。其所采用的数字电源技术可帮助实现高效率电源。
