DESCRIPTION
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 includes safety features that limit the transformer secondary voltage and protect against fault conditions which include open lamp, broken lamp and short-circuit faults.
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.
