Transient Response of Multi-Phase Power MP2978

I am using a 4 phase power supply of MP2978+MP86956. How can I simulate the response of this solution to load changes from 0 to 120A during the design stage?
After checking the your website, it seems that there are no relevant simulation models available? Is there any other way?

Hello @slade ,

Since the MP2978 is not on our website, kindly submit a ticket through the provided link to reach out to the MPSnow team directly: MPS NOW Technical Support - Contact (monolithicpower.com)
Instead of simulation this may be a case where the solution should be tested with evaluation boards.

Regards,
Jonathan
