Simple, efficient 5w chip amp

[trzn]

Hi,
I am looking for a chip amp that meets these requirements:
- Source: 12 V
- Output: ~5W
- Mono
- Very efficient in terms of energy consumption (so, I believe it should be class D amp)
- Very little components required to make it functional
- Audio output quality is not important

I cannot find anything that matches these requirements. Maybe I am missing something. I hope you can help me.

I found TPA3003D2 and TPA3007D1. The latter one is not sold in low quantities (you need to order at least 2000 units!), so I have the first one left only. But that one is a stereo amp, it requires quite a few additional components to work according to the data sheet and I have no clue how efficient it is apart from that it is class D amp.

It is stereo amp, a bit too powerful and a bit too good (I need something even simpler).

You don't mention a load impedance... I assume a 4-ohm load. How about the LM48511?

It could be either 4 or 8 ohm.

LM48511 would be great, but it operates in 3-5.5V and it has llp case, which means it is not designed for home use applications.
