My guess is it's an SCT2632A!
I have found it by a quick search on LCSC.com (no affiliation). I did a search on "632A" and tried to find the closest match. SCT seems to be the company making it.
I specifically went there, as it seems that the Blitz F7 flight controller is Chinese-designed, and that store has Chinese parts. :-)
See here for the product listing.
And here is the datasheet.
The pin-out seems to match reasonably well too:
My earlier guess would've been a MAX632 or a clone thereof, but the pin-out did not seem to match. That one too is a DC-DC converter chippo in a SOIC-8, but entirely pin-incompatible.
As an aside:
You can also easily find the on-board AT7456E in that store; which seems to be some OSD text generator. Presumably for FPV stuff? On further inspection, that one seems to be a clone of the Maxim MAX7456! On further further inspection, it is not a direct clone, it seems to have twice the character memory of the Maxim part. Still, the clone's datasheet does quite certainly borrow quite a few things from the Maxim one >:/
