这是关于emd前世今生的第二个文件夹，因为二个放在一起太大了，传不上去。资料很多，值得学习(This is about the emd incarnations of the second folder, because the two together is too big, preach not up.A lot of information, worth learning)

A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) typically containing at least two semiconductors (a diode and a transistor, although modern buck converters frequently replace the diode with a second transistor used for synchronous rectification) and at least one energy storage element, a capacitor, inductor, or the two in combination.
