DUAL DIMMING, EXTENDED TEMPEERATURE CCFL INVERTER MODULE
PRELIMINARY DATASHEET

Dual Drive, RangeMAX Wide Range
Dimming, Single Output Inverter. The
LXM1614 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 LXM1614 family offers two separate
brightness controls for lamp current
amplitude and duty cycle. This
innovation of dual brightness control with
extended dimming, combined with
Linfinity’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.
Dual Drive Dimming Control. The
inverters provide brightness ad-
justments utilizing standard lamp current
amplitude control as well as supporting
Linfinity’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 capability
eliminates the need for traditional
resistive heater wire methods to ensure
light output at extremely low
temperatures. The LXM1614 brightness
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
“instant-bright” feature and minimize
warm up time.
