AME, Inc. .. y nar i m i l Pre CCFL Backlight Controller n General Description The AME9002 is AME’s next generation direct drive CCFL controller. Like its cousin, the AME9001, the AME9002 controller provides a cost efficient means to drive single or multiple cold cathode fluorescent lamps (CCFL), driving 3 external MOSFETs that, in turn, drive a wirewound transformer that is coupled to the CCFL. However the AME9002 includes extra circuitry that allows for a special one second start up period wherein the voltage across the CCFL is held at a higher than normal voltage to allow older tubes (or cold tubes) a period in which they can “warm up”. During this one...
