I need to check the stability analysis of MPQ4470 using MPSmart. Below is my circuit and the error I am getting.
Can you please help me how to solve this issue.
Even after unticking “Use Pop trigger” I am getting this error and when I open the simulation window I can see that Pop trigger is default ticked.
If I need to use pop trigger will you please help me where to connect it.
Hi Hari,
Are you checking the transient? If you choose the model for load transient, it should have a custom pop trigger gate specified. Let me know if you are still unable to find it.

Hi Yu,
I need to get Bode plot of my Buck converter.
Can I use the model for load transient for obtaining the Bode Plot.

Hi Yu,
I tried using the model for load transient.Below is the circuit and error obatined.
If you don’t mind could you please confirm from your end.

Hi HARI,
Yes, you can use the load transient model, but deselect transient analysis. Would you mind sharing a screenshot of the analysis POP setting? Additionally, I believe the AC signal with the bode plot measurement is flipped.

Hi Yu,
Since you have a doubt in the orientation of Bode plot measurement,I changed the orientation and checked but error remains same.Please see the below image,it contains POP setting and my circuits.

Hi HARI,
Have you tried getting rid of the bottom device and simulating with one device at a time?

Hi Yu,
I tried all the options but failed.
Could you please check from your end.
