Tripath will sell the chips to you directly from thier sales department. I am currently working on an advanced four channel class-T amplifier that uses the TA0102A driver. The power supply is a totally custom switching supply. I have made circuit boards for them and the amplifier section works well. It is very tricky trying the circuit boards on this project if you have no experience with routing with this type of technology.

Also the tripath modules do not operate from PWM technology....it is a DSP alogoritm and resembles a spread spectrum signal more than a fixed frequency PWM.

Good luck with the search.
