CCFL Backlight Controller  
AME9001  
n General Description  
n Pin Configuration  
The AME9001 controller provides a cost efficient means  
to drive single or multiple cold cathode fluorescent lamps  
(CCFL). Specifically the AME9001 drives 3 external  
MOSFETs that, in turn, drive a wirewound transformer  
that is coupled to the CCFL.

The AME9001 includes features such as soft start, duty  
cycle dimming control, and fault detection. It is designed  
to work with input voltages from 7V up to 24V. When
