单线 256 级灰度三通道恒流 LED 驱动 IC

WS2811是三通道LED驱动控制专用电路，芯片内部包含了智能数字接口数据锁存信号整形放大驱动电路，还包含有高精度的内部振荡器和12V高压可编程定电流输出驱动器。 同时，为了降低电源纹波，3个通道有一定的延时导通功能，这样在帧刷新时，可降低电路纹波。芯片采用单线归零码的通讯方式，芯片在上电复位以后，DIN端接受从控制器传输过来的数据，首先送过来的24bit数据被第一个芯片提取后，送到芯片内部的数据锁存器，剩余的数据经过内部整形处理电路整形放大后通过DO端口开始转发输出给下一个级联的芯片，每经过一个芯片的传输，信号减少24bit。芯片采用自动整形转发技术，使得该芯片的级联个数不受信号传送的限制，
