Hello to all,
Today I was looking for a setting in WeBench, want to enable automatic pic of same transistor for both, High and Low side transistors. Here is the sample schematics:
It uses two N-Chan NexFET transistors CSD17303Q5 and CSD18509Q5B. From the money perspective it might be cheaper to put different transistors, when manufacturing really big quantities, but if we plan to make lets say 100 pcs of DC-DC converters - it would be more reasonable to have similar transistors (this would me a bigger quantity for the part). But in WeBech I found that I can only replace transistors in pairs, not by one of pair. Is there any technical issue with using same transistor on both sides ?
Another thing that I am missing in WeBench - to select the size of SMD capacitors/resistors/coils, so all of them would be one size (for example 0805). This is needed in case if a designer has a limited machinery, which can only pic and place 0805 or different size parts. Now I had to pick every part, just to have the right size, for big schematics it can be very time consuming. But I guess this should be forwarded to some other part of this forum...
