morning folks!

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