APA102 5050 White LED Chip

General Description

APA102 is a type ic for the three-color White Diming control strip

and string ,This ic using the CMOS process to provide three- color White

LED output driver to adjust the output with 256 gray scale and 32 brightness

adjustment ,APA with 2 signal output way , one is clock ,another is data,

the clock and data is synchronizated ,so that the crystal cascade piece of output

movement is sychronizated .

  • Feature

    CMOS process,low voltage ,low consumption

    Synchronization of two-lane

    Choose positive output or negative White three-color LED output
