DESCRIPTION
Dual Drive, RangeMAX Wide Range Dim-
ming, Single Output Inverter.
The LXM1614 series of Direct DriveTM CCFL
(Cold Cathode Fluorescent Lamp) Inverter
Modules is specifically designed for driving LCD
backlight lamps.
Although similar to the
RangeMAX LXM1612 wide range dimming in-
verters, the LXM1614 family offers two sepa-
rate brightness controls for lamp current am-
plitude and duty cycle. This innovation of dual
brightness controls with extended dimming,
combined with Linfinity’s high efficiency Di-
rect Drive topology provides the industry’s most
feature rich, small form factor inverter avail-
able. The wide range dimming provides ex-
ceptional 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 adjustments
utilizing standard lamp current amplitude con-
trol as well as supporting Linfinity’s RangeMAX
wide range dimming technique. Combining
both brightness controls into a single inverter
supports the “self heating” lamp technology by
using a “boost” current feature and still offers
duty cycle control for low brightness opera-
tion. This controlled overdrive capability elimi-
nates the need for traditional resistive heater
wire methods to ensure light output at ex-
tremely low temperatures. The LXM1614 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 uti-

lize this “instant-bright” feature and minimize
warm up time.
RangeMAX Digital Dimming Technique.
Digital dimming provides flicker-free brightness
control in any wide range dimming applica-
tion. Dimming ratios greater than 100:1 can be
achieved. A video synchronization feature al-
lows wide ratio dimming without the display
disturbances and interference seen with com-
petitive products. The resultant “burst drive”
that energizes the lamp was designed specifi-
cally to ensure that no premature lamp degra-
dation occurs. Even in overdrive boost mode,
the waveform is carefully controlled to mini-
mize the effects detrimental to lamp life. Indi-
vidual panel specifications should be referenced
for specific thermal and electrical parameters.
Direct Drive Technology. The module
design is based on the Direct Drive topology,
which provides a number of cost, performance,
and form factor advantages. The LXM1614
series inverters eliminate the classic resonant
inductor/capacitors, and integrate the wide
range dimming logic into the controller.
Additional Features. Other benefits of this
new topology are fixed-frequency operation
and secondary-side strike-voltage regulation.
Strike-voltage regulation minimizes corona dis-
charge in the output transformer and related
circuitry, providing longer life and higher reli-
ability. All LXM1614 modules feature both open
and shorted lamp protection. The dual drive
LXM1614 is fully customizable (electronically
and mechanically) to specific customer require-
ments.
