The Quad Output Module LXM1640-01 Ideal for Desktop and Industrial Applications. The LXM1640 Direct Drive^TM Cold Cathode Fluorescent Lamp (CCFL) Inverter is a single module designed to drive four lamps and is targeted for use with desktop Liquid Crystal Display (LCD) and industrial LCD panels typically ranging in size from 14-inches to 21-inches. This four output inverter is the ideal solution to power virtually any four lamp application.

Direct Drive Technology. The module LXM1640-01 design is based on a new Direct Drive topology, which provides a number of cost and performance advantages. The LXM1640-01 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 op-erating at near normal brightness in the event that a lamp fails. This allows the display to remain "on-line" until lamp replacement is convenient.Quad Module Uses Standard Power Supply. The LXM1640-01 module uses a standard 12V input supply. It also ensures nominal power consumption with 4 lamps requiring only 16 watts. Lamp current is fully regulated with respect to input voltage and output impedance variations.

Dimming Features. The LXM1640-01 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 LXM1640 modules feature both output open and short-circuit protection.
