WEBENCH® Tools/TPS7A47: Simulating design with TPS7A4701

Tool/software: WEBENCH® Design Tools

Hi team,

My customer was trying to use webench to simulate a design where they put the TPS7A4701 after a switcher to supply a clean 28V output for some sensitive RF circuitry. For whatever reason, the only version that is webench enabled is the TPS7A4700 which can only output up to 20V. 

Is there some way we can simulate this in webench? 

thanks,

Brian
