Third Generation Ccfl Controller

The LX1689 is the latest generation Direct Drive CCFL (Cold Cathode Fluorescent Lamp) Controller. It uses new circuit design techniques (patents pending) and combines digital and linear circuits with an advanced BiCMOS process to create a more complete controller in a small package. When compared to the original LX1686 design, identical module applications use from 12 to 30 less components. New functions and enhancements have been added to make the LX1689 even easier to use. The on-chip PLL circuit used to synchronize the digital dimming burst frequency to the Video frame rate, as used in the LX1686 is replaced with a programmable Counter This Counter CAN divide the Video controller horizontal sync pulse, other external Clock source or the internal chip Clock source to generate the burst frequency.
