ET6290 is a constant current LED driver circuit with PWM modulation function, ET6290 built-in 9 independent low resistance color LED drive
Dynamic channel, the output current through the PWM byte programming to achieve the 256- order brightness, to form a variety of colors. Each channel in the voltage headroom
When 0.35V is, it can provide about 40mA current.
