Step up Voltage design

I would like to ask is it’s is possible to use the tool in a step up voltage design, for example, I want to use a 1:n transformer, and in the design tool it’s only having n:1 turns ratio with a max output voltage of 90V, as I indicated in the picture.
Is there any possibility of using a 1:n turns ratio?

Hi joehu100,

What design tool are you linking? Can you provide the url?
I believe there should be a step up design.


its LLC design tool
here is the url

Unfortunately, this tool only allows for step down design.

Ok, thanks for your kindly response
