LX1688規(guī)格書詳情
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.
