Digital Dimming Ccfl Controller Ic

The LX1686 Backlight Controller IC provides all the control functions needed to implement Linfinitys direct drive in- verters used to operate cold cathode fluo- rescent lamps (CCFLs). This IC CAN be used to control single or multiple-lamp configurations. CCFLs are used for back or edge lighting of liquid crystal flat panel Displays (LCDs) and typically find appli- cation in notebook computers, web browsers, automotive and industrial in- strumentation, and entertainment sys- tems. The LX1686 includes a PWM con- trolled lamp current burst circuit that CAN provide a >100:1 dimming range from a simple zero to 2.5V potentiometer in- put. The PWM dimming burst rate is easily synchronized to the LCD panels frame rate to prevent interference from optical beat frequencies.                  T HE I NFINITE P OWER OF I NNOVATION LX1686 Safety and reliability features in- clude a new dual feedback contol loop that permits regulation of maximum lamp strike voltage as well as lamp current. Regulating maximum lamp voltage per- mits the designer to provide for ample worst case lamp strike voltage while at the same time conservatively limit maxi- mum open circuit voltage.
