While not entirely about choosing the best FETs, there is a good general
article about class D audio amplifier design in the most recent issue of
Analog Dialog (from Analog Devices).

Can anyone help? I am not certain on how to weed my way through the
very broad offering of MOSFET's. The application is for class-D audio
amp. Things like gate charge have me a little lost. Rds makes sense
in that it affects the power consumed in the fets. Ramp time and
ton/toff have me a tad confused also. Why don't the manufactures list
a ton min? They seem to always list Ton max, though.
I am open to any suggestions.
thanks
