2-Channel RGB Constant Current LED Driver with Ilumination - BD2802GU

The BD2802GU is a RGB LED driver specifically engineered for decoration purposes. This RGB driver incorporates lighting patterns and illuminates without imposing any load on CPU. This RGB driver is best-suited for illumination using RGB LEDs and decoration using monochrome LEDs. .In addition, this RGB driver has been successfully miniaturized through the use of a chip size package.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
