AME9001

n General Description

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.

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.

please look at the AME9000.
