DMX512A-PF串联DMX解码驱动芯片

 

产品简介(DMX512A-PF

     DMX512PF是单线传输三通LED驱动控制专用芯片,采用DMX512(1990)通信协议。芯片内含电源稳压电路,信号解码模块,数据缓存器,内置恒流电路,用户通过调节REXT管脚外接电阻调整恒流输出的PFM电流,也可通过外接电阻调节其他的电流值,输出驱动采用专利SPFM 技术,以及内置振荡器,支持输出端极性反转。

 

DescriptionDMX512A-PF:

DMX512PF is one chip with PFM, signal analysis and driving function, the data format follows the DMX512(1990) agreement. This chip is specially designed for LED lighting and decoration use. This chip is built in with clock circuit, decodemodule, buffer storage,3 channels constant flow driver (the electric current can be controlled by the resistance set outside) together with the Oscillator who make the PFM works.
