AME9003 CCFL Backlight Controller

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 transfo.

AME9003 Features

* a soft start AND soft finish on each dimming cycle edge in order to minimize any audible vibrations during the dimming function. The AME9003 also includes features such as, dimming control polarity selection, undervoltage lockout and fault detection. It is designed to work with input voltages from 7
