The LXM1624-12-6x is a Dual 6W Output Direct Drive™ CCFL (Cold Cathode Fluorescent Lamp) Inverter Module specifically designed for driving LCD backlight lamps. It is ideal for driving typical 10.4” to 15” panels. The modules are available with a dimming input that permits brightness control from either a DC voltage source or a PWM signal or external Potentiometer. The maximum output current is externally programmable over a range of 5 to 8m A in 1m A steps to allow the inverter to properly match to a wide array of LCD panel lamp current specifications. LXM1624 modules unlike the LXM1623 series does not provide wide range ‘burst’ mode dimming, rather dimming is provided by amplitude control of the output current waveform, this limits the potential dim range to typically less than 5:1.
For applications not requiring wide range dimming, amplitude control results in lower ripple on the input supply and reduced potential transient noise...
