摘要
发光二极管(LED)具有耗能少、寿命长、成本低等特点,近年来得到广泛应用。介绍了一种基于MAX1916芯片的亮度可调的LED驱动电路,利用改变脉宽的方法来改变LED的发光强度。
Recently, LED has been applied widely. It has the characteristics of less consumption, longer life and lower cost. This article will introduce a sort of drive current of LED which is based on MAX1916.It adjusts the brightness of LED by changing the breadth of impulse.
