基于iW3614的LED调光电源设计

Design of LED Dimming Power Supply Based on iW3614

可调光LED驱动是近年来照明界关注的焦点,文章首先从可控硅调光工作原理入手,接着详细分析了iW3614这颗LED专用调光芯片各功能模块的工作过程,最后给出反激电源几个关键器件的计算方法。

Dimmer LED driver is the focus of lighting industry in recent years.Firstly,this paper started with the principle of thyristor dimmer,then analysed the working process of each functional module of iW3614,which was a special dimmer chip for LED,and finally gave the calculation method of several key components of flyback power supply.
