DESCRIPTION
Microsemi’s LX6512 is a cost effective, Direct Drive CCFL (Cold Cathode Fluorescent Lamp) controller. The integrated controller is optimized to drive CCFL’s (Cold Cathode Fluorescent
Lamps) using either resonant full bridge inverter topology or push-pull Direct Drive configurations.
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 architecture is also coupled with a wide dimming range capability.
