DESCRIPTION
The LXMG1626-05-66 is a 10W Dual
Output
Direct
Drive™
CCFL
(Cold
Cathode
Fluorescent
Lamp)
Inverter
Module
specifically
designed
to
be
compatible with a variety of LCD panels:
A number of NEC and a few Optrex,
Prime View, Au Optronics, and other
panels that have both lamps on one side of
the panel and use a single common lamp
return wire with non standard output
polarity. LXMG1626 modules provide the
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 10 to
14mA in 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 RangeMAX™
Digital Dimming
Technique provides flicker-free bright-
ness control in any wide range (typically
100:1+) dimming application.
The design of the resultant “burst
drive” that energizes the lamp specifically
ensures
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.
The
modules
design
utilizes
Microsemi’s
LX1691B
backlight
controller, which provides a number of
cost and performance advantages due to
the controller’s high level of integration.
A
12V
input
supply
version
(LXMG1626-12-66) is also available.
Other benefits of this new topology
are:
stable
fixed-frequency
operation,
secondary-side strike-voltage regulation,
and both open/shorted lamp protection
with fault timeout.
