convert the DC voltage from a fixed 12V
supply directly to high frequency, high-
voltage waves required to ignite and
operate CCFL lamps. A 5V input inverter
is also available; LXM1612-05 series.
modules design is based on a new Direct
Drive topology, which provides a number
of cost and performance advantages.
of this new topology are fixed-frequency
operation, secondary-side strike-voltage
regulation, and both open and shorted
lamp protection. If lamp fails to strike the
inverter will timeout and shutdown.
