DESCRIPTION

The LX1686E Backlight Controller IC provides all the control functions needed to implement Microsemi’s direct drive inverters used to operate cold cathode fluorescent lamps (CCFL’s). This IC can be used to control single or multiple-lamp configurations. CCFL’s are used for back or edge lighting of liquid crystal flat panel displays (LCD’s) and typically find application in notebook computers, web browsers, automotive and industrial instrumentation, and entertainment systems.
