GENERAL DESCRIPTION
Specifically the AME9001 drives 3 external MOSFETs that, in turn, drive a wirewound transformer that is coupled to the CCFL. When disabled the circuit goes into a zero current mode. For applications that use a piezoelectric transformer please look at the AME9000. n Pin Configuration 24 23 22 21 20 19 18 17 16 15 14 13 AME9001 1 2 3 4 5 6 7 8 9 10 11 12 AME9001 24PIN QSOP 1.
