LXM1612-12-xx
12V Highly-Integrated, Digital Dimming CCFL Inverter Module
PRELIMINARY DATASHEET
RangeMAX Wide Range Dimming,
Single Output Inverter. The LXM1612-
12-xx series of Direct Drive⢠CCFL
(Cold Cathode Fluorescent Lamp)
Inverter Modules are specifically
designed for driving LCD backlight
lamps.
RangeMAX Digital Dimming
Technique. Digital Dimming provides
flicker-free brightness control in any
wide-range dimming application.
The modules are equipped with a
dimming input that permits brightness
control from either an external
potentiometer, DC voltage source, or
PWM signal. The resultant âburst driveâ
that energizes the lamp was designed
specifically to ensure that no premature
lamp degradation occurs.
Input Voltage Range. The modules
convert DC voltage from the system
battery or AC adapter directly to high-
frequency, high-voltage waves required
to ignite and operate CCFL lamps. A 5V
input inverter is also available
(LXM1612-05-xx).
Direct Drive Technology. The module
design is based on a new Direct Drive
topology, which provides a number of
cost and performance advantages.
Additional Features. Other benefits of
this new topology are fixed-frequency
operation and secondary-side strike-
voltage regulation and all LXM1612-12-
xx modules feature both open and
shorted lamp protection.
