I've never seen a switching power supply that ran at 1Mhz.

Just because you've never seen it doesn't mean it doesn't exist or is
not in common use. Here's your citation, note that the article is dated
2002.

"SMALLEST, 3V INPUT, 1MHz, 92% EFFICIENT DC-DC STEP-DOWN DELIVERS 10A"

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.
