Hi Guys,
Does anybody know any good tutorials/links on designing and testing high power SMPS and DC-DC Converters?
Thanks.

Your best friends are converter datasheets, each of them offer multiple example designs and shows you how to calculate everything.

Switching regulators for poets has always been one of my favorites. http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1154,C1002,C1223,P1209,D4120

Ok thanks for the info, guys. That linear link is very useful.
UnixWhore, any good product/datasheet comes to mind?

My advice is pick a popular converter IC to begin with, one that suits your end goals, and read everything available on it (application notes, datasheet, forum posts, etc...). While most of the information will be specific to that particular IC, you will quickly see how to relate all this to other designs. Also, make sure you start with converters that have EXTERNAL switches, as switch selection and topology design is 50% of the design workload.

online SMPS design calculator

just select suitable topology and input your requirements. get calculated magnetics details and simulated waveforms.

One of the best is a now semi-ancient tutorial by Jim Williams on the Linear Tech web site: their AN25 - "Switching Regulators for Poets":

What would you do with an AVR interfaced to a DC/DC converter?

Something like a voltage multiplier or divider? Or maybe something like a converter between different serial protocols (RS232 - TTL, CMOS - RS232, etc.)

There are stand-alone voltage doublers or inverters from Maxim. Much like the voltage converter in RS232 interface chips. It can deliver only a few milliamperes, though (see Max1682 as an example). I like MAX660 which will either double or invert, max 100mA. That is, assuming that I like Maxim, and I don't particularly.

Isn't there an Atmel app. note that shows how to use a Tiny to make a buck converter?

Yes, you can find it on the Atmel web site.

Look at the BC100 documentation for schematics and code for several buck converters.
