DIGITAL DIMMING DUAL LAMP CCFL INVERTER MODULE

DESCRI PTI O N
The LXM1621 Direct Drive CCFL
(Cold
Cathode
Fluorescent
Lamp)
Inverter
Modules
are
specifically
designed for driving two lamp LCD
backlight displays.
Similar
to
the
LXM1620,
the
LXM1621 excels in applications where
critical parameters include very wide
range dimmability, high efficiency, and
reliable fail-safe design in a small form
factor.
These 12 volt modules are
specifically designed with desktop and
industrial applications in mind.
Unlike the LXM1620 or any traditional
dimming CCFL inverters, the LXM1621
provides the designer a vastly superior
display
brightness
range.
100:1+
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
operating capability(i.e. “night readable”).
Digital dimming provides flicker-free
brightness control in any wide-range
dimming application.
Incorporation
of
a
video
synch-
ronization
feature
allows
wide
ratio
dimming without the display disturbances
and interference seen with competitive
products.
The modules are equipped with a
dimming input that permits brightness
control from an external potentiometer or
DC voltage source. The resultant “burst
drive” that energizes the lamp was
designed specifically to ensure that no
premature lamp degradation occurs (see
the “How RangeMAX works” section).
The module design is based on a new
Direct Drive topology, which provides a
number
of
cost
and
performance
advantages.
Linfinity’s multiple lamp
inverters
include a built in connector array for the
most common LCD lamp configurations.
Other benefits of this new topology are
fixed-frequency operation and secondary-
side strike-voltage regulation.
The LXM1621 is fully customizable
(electronically
and
mechanically)
to
specific customer requirements.
