WEBENCH® Tools/LMR14050: Webench Design unstable

Genius 17165 points

Part Number: LMR14050
Other Parts Discussed in Thread: LMR14020, LMR14030

Tool/software: WEBENCH® Design Tools

Dear all

Starting a Webench-Design for the LMR14050 I get the message: "Design Unstable"

----------------------

Doing a Webench-Design with the LMR14020 diode power dissipation is indicated is zero.

Please comment

Best regards

----------------------

PS: Can I add multipleWebench_LMR14020_03092017.pdf simulations to my printout report ?

I think the LMR14050 can work in 7~30Vin,5Vout,1A. Maybe the WEBENCH has some mistake.I will double check with the WEBENCH team.

Hi Ue,

can you share us the Webench design so we chan check what's wrong with it?

Hi Andy

Thank you for the quick reply. The PDF of my LMR14020 design is attached to my first post.

Hi Mao

Thank you for the quick reply.

Webench will not work with the LMR14050, regardless of the output current.

Best regards

Hi Ue,

We have resolved this issue. The changes will reflect on ti.com in couple of days.
I will let you know once this is released to ti.com.

Hi Mahantesh

Thank you for working on this issue. The simulation is now possible.

However, the Diode Power Dissipation in the Operating Values table is still indicated as zero.

Can you fix this ?

... and I have this additional question:

Is it possible to include multiple simulations in the printout report ?

Best regards

Hi Ue,

The issue for Diode Power dissipation is fixed now. It will reflect on ti.com by next week.

Currently on Webench multiple simulations in the same printout report is not available. Only one simulation report will come for each test bench.

Hi Mahantesh

Thank you for the quick reply.

It would be very helpful to be able to include muliple simulations in the printout.
So hopefully you can work on this feature as well.

Best regards

Hi Mahantesh

This is still not resolved, are you working on it ?

And please make sure you correct this for the whole family, LMR14050, LMR14030, LMR14020.

Having the diode dissipation being displayed correctly in the Operating Values table is critical.

Thank you and best regards
