PRODUCTION DATASHEET

The LXM1623-05-44 is a Dual 4W RangeMAX Digital Dimming Output Direct Drive CCFL Cold Technique provides flicker-free Cathode Fluorescent Lamp Inverter brightness control in any wide range Module specifically designed to be typically 50:1+ dimming application. compatible with the Sharp LQ104S1DG21 The resultant “burst drive” that / 51 LQ121S1DG31 / 41 as energizes the lamp is designed well as the Samsung LTM121SI-T01 specifically to ensure that no premature or similar dual lamp displays that lamp degradation occurs, while allowing have both individual lamp output significant power savings at lower dim connectors on the top side of the panel levels.

LXM1623 modules provide the modules convert DC voltage from designer with a vastly superior display the system battery or AC adapter directly brightness range. This brightness range is to high frequency, high-voltage waves achievable with virtually any LCD display. required to ignite and operate CCFL
