C OM The LXM1623-05-4x is a Dual 4W Output Direct Drive™ CCFL (Cold Cathode Fluorescent Lamp) Inverter Module specifically designed for driving LCD backlight lamps. It is ideal for driving typical 6.4” to 10.4” TFT panels. LXM1623 modules provide the designer with a vastly superior display brightness range. This brightness range is achievable with virtually any LCD display. 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 6.5mA in 0.5mA steps to allow the inverter to properly match to a wide array of LCD panel lamp current specifications. RangeMAX Digital Dimming Technique provides flicker-free brightness control in any wide range typically (50:1+) dimming application. The resultant “burst drive” that energizes the lamp was designed specifically to ensure that no premature lamp degradation occurs, while allowing significant power savings at lower dim levels. The modules convert DC voltage from the system battery or AC adapter directly to high frequency, high-voltage waves required to ignite and operate CCFL lamps. A 12V input inverter is also available (LXM1623-12-4x), as well as 6W versions (LXM1623-xx-6x) for driving larger higher voltage panels. The modules design is based on Microsemi’s new LX1689 backlight controller, which provides a number of cost and performance advantages due to the controller’s high level of integration. Other benefits of this new topology are stable fixed-frequency operation, secondary-side strike-voltage regulation and both open/shorted lamp protection with fault timeout. ƒ Externally Programmable Maximum Output Current ƒ Easy to Use Brightness Control ƒ RangeMAX Wide Range Dimming ƒ Output Open & Short-Circuit Protection and Automatic StrikeVoltage Regulation and Timeout ƒ Fixed Frequency Operation ƒ Rated From -20 to 70°C ƒ UL60950 E175910 APPLICATIONS ƒ High Brightness Displays ƒ Portable Instrumentation ƒ Desktop Displays ƒ Industrial Display Controls BENEFITS ƒ Smooth, Flicker Free 2%100% Full-Range Brightness Control ƒ Programmable output current allows inverter to mate with a wide variety of LCD panel’s specifications ƒ Output Open Circuit Voltage Regulation Minimizes Corona Discharge For High Reliability IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com Protected By U.S. Patents: 5,923,129; 5,930,121; 6,198,234; Patents Pending PRODUCT HIGHLIGHT UNIVERSAL DIMMING INPUT "PWM", VDC, OR POTENTIOMETER DC Voltage Source Potentiometer PWM Signal 2 3 SELECTABLE MAXIMUM OUTPUT CURRENT 5MA TO 6.5MA RMS PACKAGE ORDER INFO 1 PART NUMBER LXM1623-05-41 LXM1623-05-42 LXM1623-05-43 Copyright © .
