capabilities of the Microsemi’s highly
integrated
controller the inverter allows a wider input
voltage range (9V to 16.8V) and wider
lamp output voltage range 390V to 790V
compared to Microsemi’s existing Direct
Drive™ inverter solutions.
automatic brightness control an ‘S’ version
(LXMG1813-12-6xS)
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).
