industrial applications in mind.
traditional dimming CCFL inverters, the
LXMG1621 provides the designer a
vastly superior display brightness range.
100:1+ brightness range is achievable
with a standard LCD display (see Product
Highlight).
provides exceptional display readability at
less than 1% of full brightness, allowing
both power savings and low ambient light
