need an audio amplifier

I need a class AB or D audio amplifier that can output at least 5W on a low voltage supply (3.3V would be ideal, 5V is fine, i'd like to keep it below 7.5)

Anybody know of such a thing?
 
Try doing the sums - you need either:

1) An inverter to increase the supply voltage.

2) A VERY, VERY low impedance speaker.

3) A VERY, VERY low impedance speaker coupling transformer.
