CCFL INVERTER
(For Quad Tube Applications)
GENERAL DESCRIPTION
The AC8-V2-1694 is designed to power typically 4
CCFLs up to power levels of 20 Watts from a nominal
+12 VDC source.
Intensity control is accomplished by the user providing
DC voltage level at PIN 6 of CON1.
Enable control is accomplished at pin 5 of CON1.
A +5V reference voltage is available at PIN 7 of CON1
for external use.
The PWM dimming frequency of the inverter can be
synchronized to the LCD frame rate via PIN 8 of CON1.
All outputs are open and short circuit protected.
