DESCRIPTION
The LXM1621 Direct Drive™ CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving two lamp LCD backlight displays.
Similar to the LXM1620, the LXM1621 excels in applications where critical parameters include very wide range dimmability, high efficiency, and reliable fail-safe design in a small form factor. These 12 volt modules are specifically designed with desktop and industrial applications in mind.
Unlike the LXM1620 or any traditional dimming CCFL inverters, the LXM1621 provides the designer a vastly superior display brightness range. 100:1+ brightness range is achievable with a standard LCD display (see Product Highlight). Our wide range dimming provides exceptional display readability at less than 1% of full brightness, allowing both power savings and low ambient light operating capability(i.e. “night readable”). Digital dimming provides flicker-free brightness control in any wide-range dimming application.
