PRODUCTION DATASHEET
DESCRIPTION
Dual Drive, RangeMAX⢠Wide Range
Dimming, Single Output Inverter. The
LXMG1614E series of Direct Driveâ¢
CCFL (Cold Cathode Fluorescent Lamp)
Inverter Modules is specifically designed
for driving LCD backlight lamps.
Although similar to the RangeMAX
LXMG1612 wide range dimming
inverters, the LXMG1614E family offers
two separate brightness controls for lamp
current amplitude and duty cycle. This
innovation of dual brightness control with
extended dimming, combined with
Microsemiâs high efficiency Direct Drive
topology, provides the industryâs 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.
Dual Drive Dimming Control. The
inverters provide brightness ad-
justments utilizing standard lamp current
amplitude control as well as supporting
Microsemiâs RangeMAX wide range
dimming technique. Combining both
brightness controls into a single inverter
supports the âself heatingâ lamp tech-
nology by using a âboostâ current
feature and still offers duty cycle control
for low brightness operation. This
controlled overdrive capability
eliminates the need for traditional
resistive heater wire methods to ensure
light output at extremely low
temperatures. The LXMG1614E bright-
ness controls support temperature
monitoring with look-up table
applications by accepting either a PWM
input or DC voltage. Large panel lamps
with greater thermal inertia can also
utilize this âinstant-brightâ feature and
minimize warm up time.
