Current Control Sample Time of CRD07500AA12N-FMC

Hello,

I have a question regarding the CRD07500AA12N-FMC design. On the page of this reference design, it's noted that the switching frequency of the module is up to 100 kHz. Given the fact that this reference design utilizes AMC1303M0520DWVR delta-sigma modulators for the current measurements, and TMDSCNCD280039C MCU, can you tell me if 100 kHz switching frequency is obtainable in the current control closed-loop mode, i.e. can this delta-sigma modulators-MCU combination produce current measurements information every 1/100 kHz = 10 us? Have any current closed-loop tests done with this reference design?

Best regards,
