XRP7714是一款四输出脉宽调制(PWM)分级降压(step down)DC-DC控制器,并具有内置LDO提供待机电源。该器件在单个IC上为电池供电的产品提供了整套的电源管理方案,并且通过内含的I2C串行接口进行整体的编程配置。XRP7714器件的每一路输出电压的编程范围是0.9V~5.1V,此范...
电源待机能耗规范术语解释: 静态待机模式是指产品被关闭不执行任何常规功能但仍然与电源连接的空载状态,此时仅为低功耗微控制器和唤醒电路供电。比如有唤醒功能的电脑等电子产品,该微功耗电源在静态待机状态下功耗小于6mW,比能源之星静态待机功耗2.0和EuP标(300mW)还要低50倍,这么低的静态待机功耗...
利用推挽正激变换技术设计了DC /DC开关电源。提出了基于推挽正激变换技术的电源电路拓扑和结构,阐述了该开关电源的工作及控制原理,并利用PSp ice软件对该电路拓扑进行了仿真。实验结果表明,该开关电源输出稳定、波形理想。...
