The Dual Output Module Ideal for Desktop and Industrial Applications. The LXM1620 Direct Drive^TM Cold Cathode Fluorescent Lamp (CCFL) Inverter is a single module designed to drive two lamps and is targeted for use with desktop Liquid Crystal Display (LCD) and industrial LCD panels typically ranging in size from 10.4-inches to 17-inches. This two output inverter is the ideal solution to power virtually any two lamp application.

Direct Drive Technology. The module design is based on a new patented1 Direct Drive topology, which provides a number of cost and performance advantages. The LXM1620-01 Direct Drive inverters eliminate the classic resonant inductor and capacitors, thus reducing cost and allowing a substantial reduction in module size.

Fixed-Frequency Operation. Other benefits of this new topology are fixed-frequency operation and secondary-side strike-voltage regulation. Strike-voltage regulation minimizes corona discharge in the output transformer and related circuitry, providing longer life and higher reliability.

Fail-safe Feature For Multiple Lamp Applications. Our multi-output inverters are designed to keep your application operating at near normal brightness in the event that a lamp fails.This allows the display to remain "on-line" until lamp replacement is convenient.

Dual Module Uses Standard Power Supply. The LXM1620 module uses a standard 12V ±10% input supply. It also ensures nominal power consumption with 2 lamps requiring only 8 watts. Lamp current is fully regulated with respect to input voltage and output impedance variations.

Dimming Features. The LXM1620 modules are equipped with a dimming input that permits brightness control from an external potentiometer or DC voltage. In addition, the sleep input reduces module power to a few microwatts in shut down mode. All LXM1620 modules feature both output open and short-circuit protection.

The Most Efficient and Cost-effective Backlight Inverter for Desktop/Industrial Applications. Linfinity's proprietary Direct Drive architecture is the highest efficiency, small form factor solution for all multiple lamp applications. The LXM1620 is fully customizable (electronically and mechanically) to specific customer requirements.
