12V Quad 6W CCFL Programmable Inverter Module

The LXMG1644-12-61 is a Quad 6W
Output Direct Drive CCFL (Cold
Cathode
Fluorescent
Module specifically designed for driving
LCD backlight lamps. It is ideal for
driving typical 12.1” to 18.1” TFT panels.
The modules are available with a
dimming input that permits brightness
control from either a DC voltage source or
a PWM signal or external Potentiometer.
The maximum output current is externally
programmable over a range of 10 to 16mA
in 1mA steps to allow the inverter to
properly match to a wide array of LCD
panel lamp current specifications.

modules
LXMG1643 series does not provide wide
range ‘burst’ mode dimming, rather
dimming is provided by amplitude control
of the output current waveform, this limits
the potential dim range to typically less
than 5:1.
Lamp)
Inverter
unlike
the
For applications not requiring wide
range dimming, amplitude control results
in lower ripple on the input supply and
reduced
potential
generation. Many STN type panels are
particularly well suited for current
amplitude dimming.
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.
The LXMG1644-12-61 inverter is in-
tended for panel assemblies where lamp
pairs share close proximity with one
another and a common return (low side)
wire.
Other benefits of this new topology
are stable fixed-frequency operation,
secondary-side strike-voltage regulation
and both open/shorted lamp protection
with fault timeout.
