LXM1612-05-xx
5V Highly-Integrated, Digital Dimming CCFL Inverter Module
PRELIMINARY DATASHEET


RangeMAX Wide Range Dimming,
Single Output Inverter. The LXM1612-
05-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 “burst drive”
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
12V input inverter is also available
(LXM1612-12-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 LXM1612-05-
xx modules feature both open and
shorted lamp protection.
