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 基于MSP430F448单片机的交流数字电压表设计
描述了一种简易的交流数字电压表的系统设计。系统以MSP430F448为核心，该单片机内部集成了12位的A/D转换器，转换器带有内部参考源、采样保持、自动扫描特性，极大地简化了硬件设计。
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 ...
