3 wires RGB LED constant current driver IC, Part number is DJ5091


Except resolution of each color and drive LED output form are different between these two parts. They are major used on series LED cluster string to control color changing. Best advantage is reducing the wires usage. Reduce one or two wires from traditional application to single wire. Not only reduce the cost as well as easy to connect. Storage color pattern and transmit data by simple MCU, easy programming and maintenance. Besides the data series transmission also we can cascade the power to operate to obtain power saving. These techniques get lots of patent in many countries also.
