And what about a thing like these? ZNDIY ZB-8. This seems exactly as modular as it can get. The I. C. with everything placed. But they are all mechanic-adjustable. I skipped them first because i didn't even have the idea the potentiometers can be replaced with digital potentiometers. Can it be done there?
(That model also seems lowish, can max voltage be operated for 5 hours?.... This comes to view too: unnamed.)
The FAQ in Texas tools now got me the point – they write different solutions exist, and they can vary from more optimization available, to full “power module” board like those. And in fact maximintegrated.com has that parameter – module, but that only brings it nearer, not completely. And more importantly they don't have 10 A × 12 V.
