ISL6884 CCFL Brightness Controller NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc DATASHEET FN9265 Rev 0.00 March 9, 2006 ISL6884 controls Pulse Width Modulated Dimming for up to 8 inverters to supply power to up to 40 Cold Cathode Fluorescent Lamps (CCFL) for back lighting in large LCD displays. The ISL6884 brightness controller provides an I2C interface for dimming control, enable, status, and brightness balance. The duty cycle of all 8 DPWM outputs is adjusted with a Master Brightness Control register. The duty cycle of each of the 8 DPWM outputs can be offset from the master brightness to adjust for uniform brightness.
