designed for the driving LCD backlight

lamps for panels in the range of 3.9” to

15”.

integrated

controller the inverter allows a wider lamp

output voltage range 280V to 730V

compared to Microsemi’s existing Direct

Drive™ inverter solutions.

automatic brightness control an ‘S’ version

(LXMG1811-05-6xS)

includes a connector to mate the inverter

with an external light sensor board (the

LXMG1800_LS) which can extend the life

of the display and save power (particularly

important for battery powered products).
