LXMG1627-05-44 Datasheet | Microsemi

DESCRIPTION The LXMG1627-05-44 is a Dual 4W This allows the inverter to match the Output Direct Drive™ CCFL (Cold panel’s lamp current specifications. Cathode Fluorescent Lamp) Inverter The modules convert a DC voltage Module specifically designed to be from the system battery or AC adapter patible with the Sharp LQ104S1DG51 directly to high frequency, high-voltage /61 10.4”, LQ121S1DG41/61 12.1” as well waves required to ignite and operate CCFL as the 10.4” Toshiba Matsushita lamps. A 12V input inverter version is also LTA104D182F/183F and the Samsung available: LXMG1627-12-44. LTM121SI-T01 12.1” or similar dual lamp The module’s design utilizes displays that have individual lamp output Microsemi’s LX6512 backlight controller, connectors on one side of the panel. which provides a number of cost and LXMG1627 modules provide the performance advantages due to the designer with a vastly superior display controller’s high level of integration. brightness range. The Range MAX™ Other benefits of this new topology are Digital Dimming Technique supplies stable fixed-frequency operation, flicker-free brightness control for any wide secondary-side strike-voltage regulation range (typically 50:1+) dimming and both open/shorted lamp protection with application. fault timeout for open lamp condition. The included dimming input permits The new LXMG1627-xx-44 modules brightness control from either, a DC are designed therefore as a wider voltage source, a PWM signal or an temperature range near drop-in- external potentiometer. replacement for the LXMG1623-xx-44 The maximum output current is inverters, the major difference being the externally programmable (through the input input voltage adjustment range of the connector) over a range of 5m A to 6.5m A BRITE (dimming) pin. in 0.5m A steps.
