LX1686 Product details

Description

The LX1686 Backlight Controller IC provides all the control functions needed to implement Linfinity’s direct drive inverters used to operate cold cathode fluorescent lamps (CCFL’s).

Features

include a new dual feedback contol loop that permits regulation of maximum lamp strike voltage as well as lamp current. Regulating maximum lamp voltage permits the designer to provide for ample worst case lamp strike voltage while at the same time conservatively limit maximum open circuit voltage. An innovative new strike voltage generation technique enables the module designer to optimize high voltage transformer design for maximum operating efficiency with no power dissipating overhead to guar.
