描述 Description

Not Recommended For New DesignSee LXM1618-12-61Key Features:
• 8V to 18V Input Voltage Range
• 30% Smaller Than CS-ZVS Models
• versatile Brightness Control Input
• MicroAmp SLEEP Mode
• Open And Shorted Lamp Protection
• 8.3mm Max. Module Height, 16mm Width
• Fixed Frequency OperationSingle 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 inverters 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 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.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.
