| 11:33 | Bertl | morning folks!
|
| 12:04 | danieel | 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
