Why use boost buck driver circuit?
Because the voltage of UV LED is about 3.8V, and the battery will change from 4.2V to 3.0V during use, in order to achieve the maximum brightness output under any circumstances, we use boost & buck, and compared with the previous linear driver, its efficiency is much higher, which will make the heat smaller and the working time of the flashlight longer
