LED光源生产商和设计者经常会提到固态发光的应用,最明显的优势就像是“树上挂得很低的水果”。例如花园路径照明或者MR16杯灯常常只需要一些甚至只要一个LED。 对于低压应用来说,最通用的电压是12VDC、24VDC和12VAC,这些应用常常要用到一个Bulk调节器。

不知道大家在项目于上使用Buck-Boost芯片时,有没有这样的疑问:选用的明明是升降压变换器,也在单板上正常使用了,但是输出并不是负压! 应该很多人有过这样的设计:输入电压是2.5~5V,输出3.3V,DC-DC芯片选用的就是Buck-Boost芯片,输出也的确是正的3.3V,并不 ...
在ACDC电源中,输入电压一般是来自电网的85V-265V交流高压,而输出电压则是3.3V、5V、12V等直流低压,因此需要开关电源来实现降压。开关电源有Buck、Boost和Buck-Boost三大经典拓扑,其中Buck与Buck-Boost均可实现降压功能。 在ACDC电源中,输入电压一般是来自电网的 ...
