for

Although similar to the RangeMAX

LXM1612 wide range dimming inverters,

the LXM1614 family offers two separate

brightness controls for lamp current

amplitude

innovation of dual brightness control with

extended

Microsemi’s high efficiency Direct Drive

topology, provides the industry’s most

feature rich, small form factor inverter

available. The wide range dimming pro-

vides exceptional display readability at

less than 1% of full brightness, allowing

both power savings and low ambient light

operating capability.
