Dual Drive, RangeMAX Wide Range
Dimming, Single Output Inverter.
The
LXM1614E series of Direct Drive
CCFL (Cold Cathode Fluorescent Lamp)
Inverter Modules is specifically designed
for driving LCD backlight lamps.
Although similar to the RangeMAX
LXM1612 wide range dimming inverters,
the LXM1614E family offers two
separate brightness controls for lamp
current amplitude and duty cycle. This
innovation of dual brightness control with
extended
dimming,
Microsemi’s high efficiency Direct Drive
topology, provides the industry’s most
feature rich, small form factor inverter
available. The wide range dimming pro-
vides exceptional display readability at
less than 1% of full brightness, allowing
both power savings and low ambient light
operating capability.
combined
with
Dual Drive Dimming Control.
The
inverters
provide
justments utilizing standard lamp current
amplitude control as well as supporting
Microsemi’s RangeMAX wide range
dimming technique. Combining both
brightness controls into a single inverter
supports the “self heating” lamp tech-
nology by using a “boost” current
feature and still offers duty cycle control
for low brightness operation. This
controlled
overdrive
eliminates the need for traditional
resistive heater wire methods to ensure
light
output
at
temperatures. The LXM1614E bright-
ness
controls
support
monitoring
with
applications by accepting either a PWM
input or DC voltage. Large panel lamps
with greater thermal inertia can also
utilize this “instant-bright” feature and
minimize warm up time.
