Part Number: WEBENCH-POWER-DESIGNER
Other Parts Discussed in Thread: TPS61070

Tool/software: WEBENCH® Design Tools

Hi,

I hane two proglems of the "WEBENCH POWER DESIGNER".

1. In my design, simulation of only "2-Step Startup" is an error.

2. I can not print a report of simulation results.

 

Please advise on these issues to me.

Best Regards,

Toru

    Hi Toru-San

    Thanks for reaching us out. We are able to replicate the error while printing the report for TPS61070 of startup simulations. This has been forwarded to the concerned team. We will keep you updated on the development.  

    Meanwhile, we are able to run the 2 step startup. Please find the below snapshot for the same. Could you please try this again?

    I have created the design for TPS61070 and printed report for you (below attached). It contains all the simulations (2 step startup,steady,Input and load transient) except startup. Please let me know if this helps

    Hi Bhushan-san,

    Thank you for your reply.

    I tried the simulation on the original circuit.
    The simulation is complete.

    However, my customized circuit could not be simulated.
    I thought that the customized circuit was bad.

    I will try to find out a little more.

    Best regards,

    Toru

    Hi Toru-San,

    Thanks for the detailed information. We went ahead and added the mixed cap for Cin and Cout on the default design and ran the simulations

    (2 step startup,steady,Input and load transient except startup) for TPS61070 . Please find the report for the same below (attached). Please let me know if this helps.

    Hello Bhushan-san,

    Thank you for your reply.

    I tried the problem again with a customized design.
    The "2-step Startup" completed successfully.

    But the "PRINT REPORT" was an error.

    I have customized parts. (Resisters, caps, Inductors)

    However, not all the information has been entered (area, cost)

    Are these effects?

    Best rrgards,

    Hi Toru-San,

    For TPS61070, error while printing report is a bug. I have observed that, if we do not run startup and try to print the report it will not give an error. This has been reported to concerned team.

    Could you please run only 2step, steady, Input and load transient and then print the report? Please do not run startup

    I ran simulations (except startup) with your input condition and customized Cin / Cout/ L and was able to print the report. Please find the same below. Let me know if this helps.
