Modules specifically designed for driving
15” to 18”quad lamp LCD panels.
inputs that provide brightness control,
V_BRITE and P_BRITE.
V_BRITE pin adjusts the lamp current
amplitude with 0V providing maximum
brightness.
low frequency PWM signal which directly
controls the lamp drive waveform.
PWM
Technique provides flicker-free brightness
control over a wide range (typically 50:1+).
externally programmable using the SET

which we call PanelMatch™.
dedicated V_STATUS pin that indicates a
fault has occurred such as an open or
shorted lamp. V_STATUS is an open
drain configuration whose output is low
during normal operation. When one or
more lamps sustain a fault the other
lamp(s) will continue to operate and the
V_STATUS pin will toggle high. This
mode of operation during lamp(s) failure
is called StayLIT™ since the panel is able
to still remain on although at reduced
brightness.
