Hi, Knighty,

Not sure what your concerning points are, but I'd start with something like TPA3110D2.

If you can explain a little more what you're looking for, we can help you zero in on the appropriate TI class-D amp; we only have like 70 to choose from! :-)

Hi Don,

I am looking for Class D 15 watt x 2ch / 4 Ohm / 20 V. This is for LCD TV application.

Knighty,

If you must use 4-ohm speakers, you should probably upgrade to TPA3100D2. It has lower rds(on) in the output transistors so it will be easier for it to handle the increased current due to the 4-ohm speaker.
