I've used C2M0280120D and it works fine. Gate drive is a nuisance, but
that's true for all pure SiC parts.

 That's not SiC territory. Possibly GaN if you want a tiny MHz
switcher.
 SiC has amazingly low capacitances compared to high-voltage silicon.
But the gates have to swing to levels like +15 and -5. Fast.
 Why design a switcher, unless it's for fun. You can get a whole 2-amp
buck switcher, great internal reference, current and thermal limited,
spread spectrum, for 19 cents.

Indeed there's lots of stuff off the shelf but for the application I have in mind the it's is acting more like a low frequency self-oscillating Class D, tracking a control voltage.

Eventually some damned IC jock intgrates our fun circuits.

It's the future now, we can design our own mixed-signal ICs at the local Starbucks, the IC jocks don't have to have all the fun.

And I can integrate some other functions, too. Look at all the fun parts you get for 40 cents in small quantity. These things have been solid money-makers for me so far
