DESCRIPTION

The LX1699 is a high performance CCFL (Cold Cathode Fluorescent Lamp) controller optimized for wide input voltage range display backlighting applications.

The LX1699 brightness control architecture supports Intel’s DPST (Display Power Saving Technology) that adjusts the brightness as a function of video content.

The controller includes a built-in reference voltage regulator so it can be operated directly from the battery without the need of an external 5V supply from the system.
