morning folks!

hi Bertl.. got some time to chat? on smps for analog rails
12:06
Bertl
sure
12:06
danieel
you had that initiative to make a smps using programmable logic - did it lead to a working solution?
12:06
danieel
and does such supply serve well for use in analog rail supply? assuming a sensor runs at about 150kHz line freq
12:07
danieel
the 2M+ switching freq should provide enough granularity to avoid noise.. or no?
12:08
Bertl
we even had a GSoC student working on it: https://www.apertus.org/GSoC-completed-results-report-smart-switching-regulator-article-oct-2017
12:09
danieel
yes, that one - did it get past gsoc, to an actual integration?
12:09
Bertl
the results were kind of promising but then we decided to drop the idea mainly because of PCB space required
12:10
Bertl
i.e. existing switching solutions (PMICs) are a lot more compact than what we could do there (at least back then)
12:11
Bertl
we didn't check it on actual sensor hardware
12:12
danieel
ah, ok
12:12
Bertl
with modern FPGAs, preferably with some mixed mode capabilities, it should be a viable solution though
12:13
Bertl
and for sure it would provide a lot more flexibility to prevent noise
12:13
danieel
yes, i can imagine syncing the phase to the line rate
12:15
Bertl
yeah, or simply better balancing between different rails, etc
12:16
Bertl
thermal compensation, creative low load handling, etc
12:16
Bertl
remote measurements and adjustments
