reduced, third generation CCFL (Cold
Cathode Fluorescent Lamp) controller.
The integrated controller is optimized
to drive CCFL’s using resonant full
bridge inverter 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.
features that limit the transformer
secondary voltage and protect against
fault conditions which include open
lamp, and broken lamp faults.
