Full Bridge Resonant CCFL Controller
TM

Microsemi’s LX1692 is a cost
reduced, third generation Direct Drive
CCFL (Cold Cathode Fluorescent
Lamp) controller. The integrated
controller is optimized to drive
CCFL’s using resonant full bridge
inverter topology.
Resonant full bridge topology
provides near sinusoidal waveforms
over a wide supply voltage range in
order to maximize the life of CCFL
lamps, control EMI emissions, and
maximize efficiency. This new archi-
tecture also provides a wide dimming
range.
The
LX1692
features that limit the transformer
secondary voltage and protect against
fault conditions which include open
lamp, broken lamp and short-circuit
faults.

includes
safety
The LX1692 regulates the CCFL
brightness in three ways: analog
dimming, digital dimming, or combined
analog and digital dimming methods
simultaneously to achieve the widest
dimming range (> 60 to 1).
The LX1692 can accept a brightness
control signal that is either an analog
voltage or a direct low frequency PWM.
The LX1692 also features integrated
gate drivers for the four external power
MOSFETs.
An integrated 4V LDO powers all
internal control circuitry which greatly
simplifies supply voltage requirements.
The LX1692 is available in a 20-Pin
TSSOP and SOIC.
