Other Parts Discussed in Thread: CSD17312Q5, CSD17311Q5
Tool/software: WEBENCH® Design Tools
Somehow the webench suggested a converter design based on the LM27403 with two power FETs - CSD17312Q5 (lower FET) and CSD17311Q5 (Higher FET).
While looking at the webetch simulation it can be noticed that the SW terminal goes below -0.3v (it absolute maximum/minimum voltage) - (about -0.95v at the skew time).
This negative voltage value is apparently caused by the CSD17312Q5 "parasitic-diode".
Please update if that voltage will harm the controller (LM27403)?
If it will, please update me and the webench suggestions (regarding the reverse parasitic-diode voltage).
And if not, please note, how should I refer to the data-sheet "Absolute Maximum Ratings"?
