电源技术 DC-DC方面的资料
DC-DC 模块的电源纹波指标是一项很重要的参数。干净的电源是数字电路稳定工作的前提，也是模拟器件的各项参数的重要保障。
电源技术 如何运用DC-DC升压调节器
 
便携式电子器件(如智能手机、GPS导航系统和平板电脑)的电源可以来自低压太阳能电池板、电池或AC/DC电源。电池供电系统通常将电池串联叠置以实现更高的电压，但由于空间不足，此技术未必总是可行。开关转换器使用电感的磁场来交替地存储电能，并以不同电压释放至负载。因为损耗很低，所以开关转换器是个不错的高 ...

电源技术 DC/DC转换器的几点思考
 
什么是DC/DC 转换器? 什么是DC(Direct Current)呢?它表示的是直流电源，诸如干电池或车载电池之类。家庭用的100V电源是交流电源(AC) 。若通过一个转换器能将一个直流电压(3.0V)转换成其他的直流电压(1.5V或5.0V)，这个转换器被称为DC/DC转换器或称之为开关电源或开关调整器。
DC/DC转换器一般由控制芯 ...
