Pspice issure of LM3886

Andy Tan

Other Parts Discussed in Thread: LM3886

Customer inquiry the pspice model issue of LM3886 which can't opened successfully and I have tried to use it for simulation ,however while I open the OrCAD Capture 16.5.0 (.opj) file, it will show me warning about "file doesn't exist" ,then I try to cancel（or click OK） the dialog box ,another one would display which remind me about "Simulation profile is not properly initialized",ultimately I can't do the simulation successfully .I have tried to open the pspice model of LM3876 and it has a good performance and without any issure.

Is it the pspice model itself issue or caused by another reason？

Hi, Andy,

I'm going to move your question to the modeling e2e. We don't support the models in audio.

Andy,

I am a modeling engineer in the WEBENCH modeling team. I will look at the models and try to reproduce what you have seen. Once we can do that we should be able to suggest a solution.

Regards,

John

Andy,

I was able to reproduce what you have seen. It appears the sim profiles have been corrupted.
Deleting the existing sim profiles and making new ones seems to fix the problem. The attached project seems to work fine in v16.2 for AC and tran sims.

Please give it a try and let me know how it works for you.
Regards,
John

Hi,John,

it works for me ,according to the feedback which replied from customer that runing up in his simulation application.

thanks for your support.
