The LXMG1615
series of Direct Drive CCFL (Cold
Cathode Fluorescent Lamp) Inverter
Modules are specifically designed for
driving 8.4” and smaller LCD backlight
lamps. They also target portable displays
that rely on a single lithium-ion battery.
LXMG1615 modules provide the
designer with a vastly superior display
brightness range. This brightness range is
achievable with virtually any LCD
display.
RangeMAX
Technique.
Digital dimming provides
flicker-free brightness control in any wide
range (100:1+) dimming application.
The modules are available with a
dimming input that permits brightness
control from either a DC voltage source or
a PWM signal.

Digital
Dimming
The resultant “burst drive” that
energizes
the
lamp
specifically to ensure that no premature
lamp degradation occurs (See the “How
RangeMAX Works” section).
V
BATT
Voltage Range.
The modules
convert the DC voltage from a single li-
ion battery (3.2-4.2V) or a fixed 5V
supply directly to high-frequency, high-
voltage waves required to ignite and
operate CCFL lamps.
Direct Drive Technology.
The
modules 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, secondary-side strike-voltage
regulation and both open and shorted lamp
protection.
