CCFL Backlight Controller
n General Description
The AME9003 is AME’ s next generation direct drive CCFL controller. Like its cousins, the AME9001 and AME9002, the AME9003 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. The AME9003, like 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” .
