Slightly extending Innoswitch3-EP output voltage.
I have a design using a Innoswitch3-EP with 5V,3A for EU Mains voltage working well however I am now required to make another branch of the same form factor with 40V,0.5A. I was hoping to reuse as much of the design as possible but I am alittle bit puzzeled how to handle the VOUT voltage limitation.
I think the FWD pin voltage limit is solvable with single mains input. Do you see any safe option to clamp VOUT or supply this throw an LDO?
P.S. I do understand that there are other options that might be technically better suited but it would be really simple to reuse the same switcher.
