TLV62569: TLV62569

Part Number: TLV62569

Hello,

I am using a TLV62569 in a Buck converter circuit I have developed using EasyEDA.  I would like to run a simulation to test a switch I have incorporated in to the schematic.  EasyEDA offers a Spice simulation section using LTSpice.  My problem is the simulation wont run correctly because the TLV62569 component I am using has no Spice information available.  I have found and downloaded the TLV62569P_TRANS-PSpiceFiles from the TI datasheet for the component but am totally at a loss as to how I can use that information to update the component I have in the schematic or to find a version of the component that has the Spice info included.

I hope someone can advise or perhaps provide a link to a tutorial or vide that might talk me through my problem.

regards

    Hi Leslie,

    You can have a look at TI's Webench tool for Circuit design and for simulating the PSPICE models, you can use "PSPICE for TI" tool. You can find more information about this tool at https://www.ti.com/tool/PSPICE-FOR-TI#overview 

    Let me know if this helps.

    Thank you!

    Best regards

    Thank you for your reply and advice.  I was unaware of the PSPICEfor TI tool as I have only used the WEBENCH tool in the past and found that very helpful although it doesn't appear to allow schematic changes to be made to the schematics it uses.

    I am in Australia and have requested access to the PSPICE tool and will have to wait to see if I am given approval to use it. As I mentioned in m y post I have downloaded the PSpice files slvmbw3a.zip and slvmc19b.zip but am not sure how I am meant to use them when adding the Pspice info to a TLV62569 model.

    Hopefully I will be approved for access.

    Regards

    Hi Leslie, 

    Once you have the access to the tool, you can open the PSPICE model using this simulation software and try to run the analysis using this tool. 

    Please let me know if you have problems with the access.

    Thank you!

    Best regards

    Hello, I have now accessed and installed the Pspice for TI tool and worked through a couple of tutorials.  I have also set up a simple circuit using the TLV62569 but when I attempt to run the simulation I receive a message as shown in the attached image.  I have looked but cant find any log files attached to the Log directory and specifically cant find the session log referenced in the message.

    I hope someone can advise where I will find that log so I can try and identify my problem.

    Cheers

    Hi Leslie,

    You can find the session log in the lower left corner in  the "PSPICE for TI" start page. Please see the screenshot attached.

    If you are not able to see this option, then please check if the session log window in the "view" menu is enabled. 

    I hope this helps.

    Thanks and regards
