The LXMG1626-12-64 is a Dual 6W
Output Direct Drive CCFL (Cold
Cathode
Fluorescent
Module specifically designed to be
compatible
with
LQ150X1LGN2(A),(H), 15” or similar
dual lamp displays that have both
individual lamp output connectors on the
one side of the panel.

designer with a vastly superior display
brightness range. This brightness range is
achievable with virtually any LCD display.
The modules are available with a
dimming input that permits brightness
control from either, a DC voltage source,
a PWM signal or external Potentiometer.
The maximum output current is
externally programmable (through the
input connector) over a range of 3.5 to
5mA in 0.5mA steps. This allows the
inverter to match the panel’s lamp current
specifications, or it can be used to
purposely drive the lamps at a lower or
higher current to decrease or increase
nominal brightness.

The resultant “burst drive” that

specifically to ensure that no premature
lamp degradation occurs, while allowing
significant power savings at lower dim
levels.
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.

controller’s high level of integration.
Other benefits of this new topology
are stable fixed-frequency operation,
