Slightly extending Innoswitch3-EP output voltage.

Posted by: on Thu, 04/29/2021

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.


Best Regard

Hi Mattias,

Sorry but right now we don't have a solution on higher output voltages.

Putting a clamp on FWD/VOUT will result to confusion on controller switching detection.
