Part Number: UCC5870QDWJEVM-026
Hello,
We are currently evaluating the UCC21710QDWEVM-025. However, I believe the 10A gate drive current is too low for the speeds we intend to switch the rather large capacitance of the XM3 series of modules.
I stumbled across both the UCC5870-Q1 (15A) and the UCC5870QDWJRQ1 (30A). The demonstration board for the 5870 model, however, is only specified as 15A - half that which is it seems capable of.
Is there a reason for this?
We'd like to test the 5870 mostly because we can more easily see the difference between the 21710 model quite easily with 3x higher theoretical peak driving current into the gate capacitance.
The other is of interest as it is modelled around the XM3 - but it is not clear how this would fit to the module specifically. There seems to be a lack of documentation for some of the driver chips and their respective demonstration boards.
Do let me know if there is any comment on the above.
Best regards,
JM
