Hi Webench Team,

I'm running the simulation for LM5576. The operating condition is 50Vin, 28Vout, 1.5Aout. When I change some component values and try to check the bode plot, it doesn't work with 'Simulation Failed' error. Could you look into this?

Hi Ella

You are correct. I verified for default input condition its working fine but for specific case mentioned above its failing. We are looking into the root cause for this. We would be able to get back with more details by next week.

Umayal,

Thank you for your update. But I still run into the same problem. Maybe I misunderstand your comment. Is the fix available BY 7th July or FROM 7th July?

We are expecting next Webench release to be tentatively on 7th of July. So the fix should be available (on ti.com) on or after 7th of July. Hope this clears the confusion. Umayal will update you on this thread once the changes are available to test on ti.com.
