June 2012 XRP7620 4-Channel Adjustable Current I2C Controlled LED Driver Rev. 1.1.0 GENERAL DESCRIPTION The XRP7620 is a multi purpose 4-channel independently adjustable current sink driver. Optimized for LED backlighting and RGBW/RGBA color mixing applications, the XRP7620 can also be used as a generic software programmable current sink I/O expander. Supporting an industry standard 2-wire I2C serial interface, the XRP7620 provides full independent control of each channel and can be programmed up to a current of 31.5mA in steps of 0.5mA. Uniform display brightness is ensured through better than 3% channel to channel current matching. Five internal registers are provided to set operational configuration and individual channel current programmation.
