WEBENCH® Tools/LM2679: Simulation does not give correct Vout?

Part Number: LM2679

Tool/software: WEBENCH® Design Tools

Team,

I am just trying a Webench basic simulation for the startup sequence to try to vizualise transient overshoot.

My parameters are entered on the LM2679 product page directly: WEBENCH^® Designer LM2679

From this the simulation (keeping all default parameters) give me 1.21V Vout. Any idea why?

HI AnBer,

We are investigating this issue and will get back to you as soon as we have identified the root cause. Thanks for your patience.

Hi Nikhil,

Any update? Were you able to find the root cause?

The question is linked as well to the below post as we wanted to simulate the start-up of the LM2679 vs the other LM267x devices:

Will we be able to simulate the problem illustrated on this thread in Webench?

Thanks in advance,

Anthony
