Is there any way to fully simulate the ADP5054 with Buck 1 and Buck 2 in parallel?

Hello all,

 

I'm designing a multi-rail power supply with the ultimate goal of minimizing board area. Our current design uses LT uModules but I really like the features in the ADP505x series. I'll be doing a design which is very similar to the Kintex UltraScale refrence design in the first few pages of this (PDF) document.

 

I want to validate the design with full simulation. I've been using the ADP505x Buck Designer Excel spreadsheet, and I've exported models of single buck converters out to ADIsimPE. I see that those models note that parallel operation is not included. Is there some beta version of the model that includes the parallel operation? I'd really like to see the output of a full, dual IC power supply.

 

Thank you for your help.

 

Stephen
