Are they using aluminium substrate?. I just read 30oz copper. Oh yeah... chunky
I'll finish my layout and post it on my 3kw micro lebowski thread.
I wonder how much these fets cost I haven't looked at them yet? Anyone have a link to a supplier
You have not read it correctly , it is 3oz or 105um copper thickness with aluminum substrate , check the new image i attached , taken from the PDF file (app note).
it is really interesting to know that you are working on similar part ( the fairchild mosfet ) which is almost the same performance of the infenon part , i am interseted in seeing your progress ,
1-did you post any ??
2-and how many mosfets are you paralleling ?
3-do you use SMD aluminum /polymer capacitors , or through hole ones on a separate board
regarding the post about assembly difficulty , i think nowadays there are many shops that are willing to work with small quantities ( reflow soldering) especially with such low count of components .
