12VDC Class-D Chips

I'm planing to hide a couple of TPA3001D1 inside my laptop. They are mono BTL class D chips and they will be powered with 19V from the charger when it's plugged and with 13V from the battery when it isn't. With a couple of external speakers it should be as loud or more than most boom boxes and great for little unexpected parties anywhere.

BTW: This is a tiny SMD Texas Instrument chip: http://focus.ti.com/docs/prod/folders/print/tpa3001d1.html
