WEBENCH® Tools/LMZ10505: LMZ10505 model will not simulate in WEBENCH

Part Number: LMZ10505

Tool/software: WEBENCH® Design Tools

When I attempt to simulate a design using the LMZ10505, the schematic representation does not convert to a simulation model correctly in order to run a steady state, or transient simulation.

This appears to be an issue with the underlying model for the LMZ10505 --- but I'm not positive on that.

Any thoughts would be welcome.

    Hi Dave,

    I went onto the LMZ10505 product folder and used the WEBENCH Designer tool for application: Vin= 5V, Vout = 3.3V, Iout= 3A and was able to perform a startup simulation. Also was able to perform load transient and standby. However, I do noticed that there is an issue with simulating the bode plot which I will notify the simulation team. Can you try again to see if you are getting the same issue?

    I've attached a link to the simulation design I generated for the LMZ10505 using the condition mentioned above.

    Thank you ---
    I agree, the other types of simulation seem to work ---
    STARTUP, LOAD TRANSIENT, INPUT TRANSIENT, STEADY STATE

    I was focused on the BODE PLOT portion and that is where I encountered the error.
    Thank you for pushing this to the attention of the right people in the simulation team.

    Regards,
