CCFL INVERTER
(For Multiple Tube Applications)
GENERAL DESCRIPTION
The ACB-12-1931 is designed to power 6 CCFLs to a
nominal power level of 32.4 Watts from an input
voltage of +12V.
Intensity control is accomplished by the user providing
a variable DC voltage level at pin 7 of CON1. A DC
reference voltage (+5V) is available at pin 6 of CON1
for external use.
Enable control is accomplished at pin 5 of CON1.
All outputs are open and short circuit protected.
