Synchronous buck regulators offer high efficiency and are popular in applications in which available input voltages are 12V or less. However, as input voltage approaches 100V, wide-range-regulator design becomes more difficult, and the choice of suit…

eclipse新建maven项目时候,只出来三个文件夹,然后大都督手动添加了缺失的src/test/resource 的文件夹,最后想修改一下 Output folder的路径为 (原来是     default 啥啥的路径)随即出现了报错 解决方法:大都督通过科学搜索,终于找到问题所在:对比其他文件夹,发现了啥 看到没,那个Contains test source:显示的是NO,而java文件夹显示的是YES所以大都督秀手一挥,果断双击 这个东东,噔噔蹬蹬..... 完好无报错!!!!!———…

I bought this Raspberry Pi (model B) in spring 2013, I hadn't done too much with it except for some PyGame coding stuff. So recently, I wanted to reboot my robotic project. (For those who are not familiar with Raspbery Pi, it's a 35 dollar mini compu…

LDO Regulator High accuracy voltage regulator Vout = 2.5V * (1 + ( 5.6 / 6.8 ) ) = 4.55V Recently the author had to adapt  a standard circuit configuration  (which often uses an npn bipolar) so as to operate as a low-dropout (LDO) regulator. The circ…

The circuit in Figure 1 is a good choice if you need a power supply with high efficiency and you don't want to use expensive dc/dc-converter ICs. The heart of the circuit is IC1, the common, inexpensive LM7805 linear regulator. The external switch is…

The SEPIC (single-ended, primary-inductance-converter) topology is generally a good choice for voltage regulators that must produce an on output voltage that falls in the middle of the input-voltage range, such as a 5V output from a 2.7 to 6V input,…

Targeting use in portable-system applications that require raising a battery's voltage to a higher level, IC boost regulators often include output transistors that can drive storage inductors. However, most boost regulators' absolute-maximum input-vo…

You would normally use a series linear regulator or a dc/dc converter to obtain 3V dc from a higher supply. However, when breadboarding a concept, you may be able to use a shunt regulator, especially if a series regulator of the correct voltage is un…
