Forgive my curiosity, but what exactly prevents the SMD versions handle that much current?
Where is the biggest bottleneck?
Is there a way to modify either the part selection and/or the boards to allow for my current draw requirement?
I have tight physical space requirements, hense SMD parts are a must, through hole is too bulky. How would you go about suiting the SMD versions to handling this much current? (at least theoretically, I'm not asking to modify your existing designs).
