Description

The AME9001 controller provides a cost efficient means o drive single or multiple cold cathode fluorescent lamps CCFL). Specifically the AME9001 drives 3 external OSFETs 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 disabled the circuit goes into a zero current mode.

For applications that use a piezoelectric transformer please look at the AME9000.
