So these are not off-line SMPS, but so what? They're still switchmode
power supplies by definition. TI and several others have similar parts.
It is very likely you have one right in front of you supplying the core
voltage to the CPU in your computer.
That is so cool, I still haven't come across one yet, that I know
of. Now I know what to look for. I'll have to look at the motherboards
of several of my computers. According to the date of the article,
the things have been around for a while.
