Description

The LX1688 is a fixed frequency, dual current/voltage mode, switching regulator that provides the control function for Cold Cathode Fluorescent Lighting (CCFL). This controller can be used to drive a single lamp, but is specifically designed for multiple lamp LCD panels. The IC can be configured as a master or slave and synchronize up to 12 controllers.
