LXM1615-03-xx

RangeMAX^TM Wide Range Dimming, Single Output Inverter. The LXM1615 series of Direct Drive CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving 8.4" and smaller LCD backlight lamps. They also target portable displays that rely on a single lithium-ion battery.

LXM1615 modules provide the designer with a vastly superior display brightness range. This brightness range is achievable with virtually any LCD display.RangeMAX Digital Dimming Technique. Digital dimming provides flicker-free brightness control in any wide range (100:1+) dimming application.

The modules LXM1615-03-xx are available with a dimming input that permits brightness control from either a DC voltage source or a PWM signal.The resultant "burst drive" that energizes the lamp was designed specifically to ensure that no premature lamp degradation occurs (See the "How RangeMAX Works" section).

V_BATT Voltage Range. The modules LXM1615-03-xx convert the DC voltage from a single liion battery (3.2-4.2V) or a fixed 5V supply directly to high-frequency, highvoltage waves required to ignite and operate CCFL lamps.

Direct Drive Technology. The modules LXM1615-03-xx design is based on a new Direct Drive topology, which provides a number of cost and performance advantages.

Additional Features of LXM1615-03-xx. Other benefits of this new topology are fixed-frequency operation, secondary-side strike-voltage regulation and both open and shorted lamp protection.
