2-Channel RGB Charge Pump LED Driver with Ilumination
The BD2812GU 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. The DC/DC converter module adopts a charge pump system and rarely uses a coil. In addition, this RGB driver has been successfully miniaturized through the use of a chip size package.
