The LXM1621 Direct

TM
CCFL (Cold Cathode Fluorescent
Lamp) Inverter Modules are specifically de-
signed for driving LCD backlight lamps.
Similar to the LXM1620, the LXM1621 ex-
cels in applications where critical parameters
include very wide range dimmability, high ef-
ficiency and reliable fail-safe design in a small
form factor. These 12 volt input modules are
specifically designed with desktop and indus-
trial applications in mind.
Unlike the LXM1620 or any traditional
dimming CCFL inverters, the LXM1621 pro-
vides the designer a vastly superior display
brightness range. 1000:1+ brightness range
is achievable with a standard LCD display (see
Product Highlight). Our wide range dimming
provides exceptional display readability at less
than 1% of full brightness, allowing both
power savings and low ambient light operat-
ing capability (i.e. "night readable").
RangeMAX Digital Dimming Tech-
nique.
Digital dimming provides flicker-free
brightness control in any wide-range dimming
application. Dimming ratios as great as
1000:1 can be achieved. Incorporation of a
video synchronization feature allows wide
ratio dimming without the display distur-
bances and interference seen with competi-
tive products.
The modules are equipped with a dimming
input that permits brightness control from an
external potentiometer or DC voltage source.

RangeMAX
lamp was designed specifically to ensure that
no premature lamp degradation occurs (see
"How RangeMAX Works" Section).
Fail-safe Feature For Multiple Lamp
Applications.
Our multi-output inverters are
designed to keep your application operating
at near normal brightness in the event that a
lamp fails. This allows the display to remain
"on-line" until lamp replacement is conve-
nient.
Direct Drive Technology.
The module
design is based on a new Direct Drive topol-
ogy, which provides a number of cost and
performance advantages. The LXM1621-xx
Direct Drive inverters eliminate the classic
resonant inductor and capacitors, thus reduc-
ing cost and allowing a substantial reduction
in module size.
Universal Connector Configuration.
Linfinity's multiple lamp inverters include a
built in connector array for the most com-
mon LCD lamp configurations.
Additional Features.
Other benefits of
this new topology are fixed-frequency opera-
tion and secondary-side strike-voltage regu-
lation.
Strike-voltage regulation minimizes corona
discharge in the output transformer and re-
lated circuitry, providing longer life and higher
reliability. All LXM1621 modules feature
both open and shorted lamp protection.
The LXM1621 is fully customizable (elec-
tronically and mechanically) to specific cus-
tomer requirements.
