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.
