The document describes a backlight inverter module that is highly efficient, small and compact, with multiple outputs and low EMI. It can drive two lamps simultaneously, with adjustable lamp current, 3:1 dimming control, and features such as output short and open circuit protection. The module is suitable for applications such as desktop LCD monitors and panels, industrial LCD panels, and hi-brite displays.
The Linfinity LXM1620-xx is a Direct Drive Cold Cathode Fluorescent Lamp (CCFL) inverter module designed to drive two lamps simultaneously. It is targeted for use with desktop and industrial LCD panels ranging from 10.4 to 17 inches, utilizing a patented Direct Drive topology to eliminate resonant inductors and capacitors for a compact size and high efficiency. The module operates on a standard 12V input supply and features fixed-frequency operation with secondary-side strike-voltage regulation to ensure longer lamp life and higher reliability.
| Output Power (per Lamp) | 3W to 5W |
|---|---|
| Lamp Current (Full Brightness) | Up to 6.0mA per lamp |
The module uses a standard 12V input supply with a functional range of 10.2V to 16V.
The module is designed to drive two lamps with one module.
The module keeps the application operating at near normal brightness by adding the current from the failed lamp to the good one.
