6/5V 2W, DIGITAL DIMMING CCFL INVERTER MODULE P RELIMINARY D ATA S HEET RangeMAX™ 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 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).
VBATT Voltage Range.
The modules 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.
The Direct Drive Technology.
modules design is based on a new Direct Drive topology, which provides a number of cost and performance advantages.
Additional Features.
Other benefits of this new topology are fixed-frequency operation, secondary-side strike-voltage regulation and both open and shorted lamp protection.
