1、Module description:
MY9221 a 12 channel (R / g / b x 4) support constant current LED driver chip built in gray scale adaptive pulse density intensity modulation, operating at 3.0 volts to 5.5 V input voltage range. MY9221 including has 12 complete very open road constant current sink into output, under 17 volts and the output of 60 Ma high precision degree of the electric current to each connecting led. Three groups of output current of MY9221 can be three external resistors set. MY9221 provide information / a unique maximum 10MHz can reduce electromagnetic interference of the clock input.
2、Function Description: Drive LED lamp.
