It's a TI GaNfet lowside gate driver. Insane specs.
It's a nasty little leadless package. There's an even faster BGA
version.
I wish there was a higher-voltage version, for driving SiC parts.
Yikes, nine bucks in onesies.
That's in the noise floor for the products that we have in mind. But
it will cost a lot more than the fets we will be driving.
What's interesting is that the schematic on the data sheet seems to
show a p-channel GaN fet... on chip!
Pretty cool driving 5V into 220 pF in 650 ps, for sure.

I took that to be a regular silicon p-ch fet. Although the chip is intended
to drive GaN devices isn’t it itself regular silicon- does the datasheet
say it is fabricated from GaN?
