RangeMAX鈩?Wide Range Dimming,
Single Output Inverter.
The LXM1615
series of Direct Drive CCFL (Cold
Cathode Fluorescent Lamp) Inverter
Modules are specifically designed for
driving 8.4鈥?and smaller LCD backlight
lamps. They also target portable displays
that rely on a single lithium-ion battery.
LXM1615 modules provide the
designer with a vastly superior display
brightness range. This brightness range is
achievable with virtually any LCD
display.

Digital
Dimming
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.
The resultant 鈥渂urst drive鈥?that
energizes the lamp was designed
specifically to ensure that no premature
lamp degradation occurs (See the 鈥淗ow
RangeMAX Works鈥?section).

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.
The
Direct Drive Technology.
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.
