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.
The LX1688 includes highly integrated universal ‘PWM or DC’ dim input that
allows either a PWM or DC input to adjust brightness without requiring
external conditioning, since a single external capacitor CPWM can be used to
integrate a PWM input. Burst mode dimming is possible if the user supplies a
low frequency PWM signal on the BRITE input and no CPWM capacitor is used. The
controller utilizes Microsemi’s patented direct drive fixed frequency topology
and patented resonant lamp strike generation technique.
