DESCRI PTI O N
The
LXM1618-05-6x
is
a
Single
Output 6W Direct Drive™ CCFL (Cold
Cathode
Fluorescent
Lamp)
Inverter
Module specifically designed for driving
LCD backlight lamps.
It is ideal for
driving typical 12.1” to 15” panels.
The
maximum
output
current
is
externally programmable over a range of 5
to 8A in 1mA steps to allow the inverter to
properly match to a wide array of LCD
panel lamp current specifications. The
modules are include a dimming input that
permits brightness control from either a
DC voltage source, a PWM signal or an
external potentiometer.
LXM1618
modules
unlike
the
LXM1617 series does not provide wide
range
‘burst’
mode
dimming,
rather
dimming is provided by amplitude control
of the output current waveform, this limits
the potential dim range to typically less
than 5:1.
For applications not requiring wide
range dimming, amplitude control results
in lower ripple on the input supply and
reduced
potential
transient
noise
generation.
Many STN type panels are
particularly
well
suited
for
current
amplitude dimming.
The modules convert a DC voltage
from the system battery or AC adapter
directly to high frequency, high-voltage
waves required to ignite and operate
CCFL lamps. A 12V input inverter is also
available (LXM1618-12-6x).
The inverter’s design is based on
Microsemi’s
new
LX1689
backlight
controller, which provides a number of
cost and performance advantages due to
the controller’s high level of integration.
Other benefits of this new topology
are
stable
fixed-frequency
operation,
secondary-side strike-voltage regulation
and
both
open
and
shorted
lamp
protection with fault timeout.
