Single Output Inverter Ideal For Portable Applications. The LXM1610 series of Direct Drive^TM CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving LCD backlight lamps. They excel in applications where critical parameters include dimmability, high efficiency and reliable fail-safe design in a small form factor. These inverters are recommended for use in panels with low-voltage insulation on the lamp return wire.

Wide Input Voltage Range. The modules convert unregulated DC voltage from the system battery or AC adapter directly to high-frequency, high-voltage waves required to ignite and operate CCFL lamps. Input voltage can range from 8 to 18 volts.

Direct Drive Technology. The module design is based on a new Direct Drive topology, which provides a number of cost and performance advantages. The LXM1610-01 series Direct Drive invert- ers eliminate the classic resonant inductor and capacitors, thus reducing cost and allowing a 30% reduction in module size.

Fixed-Frequency Operation. Other benefits of this new topology are fixedfrequency 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.

Dimming Features. The LXM1610 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 LXM1610 modules feature both output open and short-circuit protection. The LXM1610 is fully customizable (electronically and mechanically) to specific customer requirements.
