电源技术 如何设计一个高效率的DC-DC转换器
Abstract: The DS1875 features a pulse-width modulation (PWM) controller that can be used to control aDC-DC converter. The DC-DC converter can then be used to generate the high bias voltages necessaryfor avalanche photodiodes (APDs). This application note describes the operation of a boost converte ...
电源技术 开关电源电路拓扑结构的选择
开关电源（直流变换器）的类型很多，从输入输出有无隔离角度，开关电源主回路可以分为隔离式与非隔离式两大类型。这两种类型中又各自包含有不同的电路拓扑种类。每种结构都有各自的特点，适用于不同的应用场合，下边将对各种开关电源拓扑结构简要叙述和比较。 ...
电源技术 四路输出开关转换器提供TFT LCD面板的电源
 
The LT®1943 is a highly integrated, 4-output regulatordesigned to power large TFT LCD panels. The LT1943employs switching regulators—instead of linear regulators—to minimize power dissipation and accommodate awide input voltage range. The wide input range, 4.5V to22V, allo ...
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 ...
