LM2596 model

Hi all

 

I'm trying to simulate a buck converter using the LM2596 simple switch regulator. This chip as a feedback reference voltage of 1.23V in the datasheets I found but Multisim only has a 3.3 and 5V feedback version of the chip. 

 

I was wondering if it would be possible to change the model specs so that the feedback voltage is 1.23V, but I do not want to fiddle with the wrong parameters.

 

It is also possible that a external model is available and if so would you maybe share the file and possibly who to create the model in multisim.

 

Thanks in advance
