LXM1612-05-03屬于光電器件的鎮(zhèn)流器逆變器。由美高森美公司制造生產(chǎn)的LXM1612-05-03鎮(zhèn)流器，逆變器逆變器是用于提供大輸出電壓的器件，通?？墒褂萌魏蔚胤降?1.5 V 至 24 V 小輸入電壓來(lái)提供 100 至 1000 V 的大輸出電壓。這些器件最常用于冷陰極螢光燈、紫外線燈和電致發(fā)光線等特定的背光照明應(yīng)用。逆變器端接方式通常是預(yù)先安裝的連接器，或者是在小尺寸板上的通孔安裝 PC 引腳。

DESCRIPTION

RangeMAX Wide Range Dimming, Single Output Inverter. The LXM1612-05-xx series of Direct Drive? CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving LCD backlight lamps.

RangeMAX Digital Dimming Technique. Digital Dimming provides flicker-free brightness control in any wide-range dimming application. The modules are equipped with a dimming input that permits brightness control from either an external potentiometer, DC voltage source, or PWM signal. The resultant “burst drive” that energizes the lamp was designed specifically to ensure that no premature lamp degradation occurs.

Input Voltage Range. 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 (LXM1612-12-xx) Direct Drive Technology. The module 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 and secondary-side strike voltage regulation and all LXM1612-05-xx modules feature both open and shorted lamp protection.
