New ContributorEN6337QA SPICE model
Do you have a SPICE model for the EN6337QA? I am not interested in the spreadsheet as that is not acceptable for Worst case circuit analysis.

New ContributorDoes you model to AC output impedance/frequency domain? Transient models are no where near as useful as average/AC models for the things that designers really care about (stability, PDN/power integrity, ripple)

Occasional ContributorHi @CEHymowitz ,
I am sorry, i can't share un-encrypted model due to the model related confidential information.
I will create the AC model for you, but need some time.
Whatever, the LTSPICE model and the stability tool are accurate to represent EN6337, but the stability tool presented bode plot maybe is not same as what you measure where the present bode plot at the nominal case but when you click the compensate button the tool will check all the other corner case.
I have enabled the Zout_closed loop model on the attached stability tool, please check IND_Ripple tab.
Please note that EN6337 has a soft inductor and the inductance value will change based on the loading current.
So the LTSPICE model is very good to model the DC analysis and the stability tool will help to adjust the loop to make sure the VR is stable.
Regards,
Mostafa
