lation, lamp current regulation, and lamp
dimming in a single power stage made up
of two pairs of low loss FET's. The FET's
drive an LC resonant circuit that feeds the
primary of a high voltage transformer with
a sinusoidal voltage.
Required L and C values in the resonant
circuit are such that very low loss compo-
nents can be used to obtain higher electri-
cal efficiency than is possible with previous
topologies.
The full bridge LXM1597-01 is optimized
to efficiently operate with up to 4 watt lamps
at input voltages of 5 volts. This module
will operate over the full 4.5V to 7V input
voltage range.
The modules are equipped with a dim-
ming input that permits full range bright-
ness control from an external potentiom-
eter, and a sleep input that reduces module
power to a few microwatts in shut down
mode.
All modules feature output open and short
circuit protection.
LXM1597-01 CCFL (cold cathode florescent
lamp) Inverter Modules are specifically de-
signed for driving LCD back light lamps in
applications where dimmability, ultra-high
efficiency, high light output, low noise emis-
sions, reliable fail safe design, and small form
factors are critical parameters. Both mono-
chrome and color displays are supported.
The modules convert unregulated DC
voltage from the system battery or AC
adapter directly to high-frequency, high-
voltage sine waves required to ignite and
operate CCFL lamps. The module design is
based on a proprietary Linfinity IC that pro-
vides important new performance advances.
Remarkable improvements in efficiency
and RF emissions result from its
single
stage
resonant inverter featuring a patent pend-
ing Current Synchronous, Zero Voltage
Switching (CS-ZVS) topology. CS-ZVS pro-
duces nearly pure sine wave currents in the
lamp enabling maximum light delivery while
reducing both conducted and radiated noise.
This topology simultaneously performs
three tasks consisting of line voltage regu-
