New and Original LXMG1618-12-42 High Performance CCFL Inverter Module for LCD Backlight Lamps Driving

Description:
- The LXMG1618-12-42 is a CCFL (Cold Cathode Fluorescent Lamp) inverter module specially designed for driving LCD backlight lamps. It is ideal for driving typical 8.4” to 12.1” panels.
- The maximum output current is externally programmable over a range of 5 to 6.5mA in 0.5mA steps to allow the inverter to properly match to a wide array of LCD panel lamp current specification. The modules are include a dimming input that permits brightness control from either a DC voltage source, a PWM signal or an external potentiometer.
- LXMG1618 modules unlike the LXMG1617 series does not provide wide range “burst” mode dimming, rather dimming is provided by amplitude control of the output current waveform, this limits the potential dim range to typically less than 5:1.
- For applications not requiring wide range dimming, amplitude control results in lower ripple on the input supply and reduced potential transient noise generation. Many STN type panels are particularly well suited for current amplitude dimming.
- The modules convert DC voltage from the system battery or AC adapter directly to high frequency, high-voltage waves required to ignite and operate CCFL lamps. A 5V input inverter is also available (LXMG1618-05-4X).
- The module design is based on new LX1689 backlight controller for Microsemi, which provides a number of cost and performance advantages due to the controller’s high level of integration.
- Other benefits of this new topology are stable fixed-frequency operation, secondary-side strike-voltage regulation and both open and shorted lamp protection with fault timeout.
