摘　　要：首先介绍了LED驱动器芯片的关键性能参数,并在此基础上阐述了16位恒定电流源LED驱动器的工作原理,设计了一种通过调节外接电阻能稳定输出10mA～50mA电流的驱动器。In this paper, the key characteristic parameters of LED Driver are interpreted first and on the basis of which the operating principle of the 16 - bit constant current source LED Driver is explained in detail. Then a LED driver supplying a stable current of 10 - 50 by adjusting an external resistor is presented.
