CCFL INVERTER
(Single Tube Application)
GENERAL DESCRIPTION
The ACE-12-1816 is designed to power 1 CCFL to a
nominal power level of 7.5 Watts.
Intensity control is accomplished by the user providing a
variable DC level at pin 4 of CON1.
Enable control is accomplished at pin 3 of CON1.
Output is open and short circuit protected.
