TINA/Spice/TPS709: No TINA Circuit Available????

Neil Albaugh

Part Number: TPS709
Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models

I cannot find a TINA circuit for the TPS709-3 or TPS709-3.3 posted on the TI website. There are "encrypted" transient models and "unencrypted" files purporting to be able to be run in TINA but, using the "TOOLS", "NEW MACRO WIZARD", neither one is able to generate a TINA model. Both return "error on line ....xx".

These problems would not occur if TI provided a working device schematic in TINA. Not only would the correct operation of the model be verified, there would also be a pre-drawn device symbol. It is then easy to copy and paste that symbol into a new circuit.

Burr-Brown/TI started off doing that with all their new analog products- what happened?

    Hi Neil,

    We have been doing our best to add as many models as possible on TI website. We try to add TINA-TI compatible models immediately after PSPICE models are released.  Also we have been adding features like SIM Export to WEBENCH where user can export his design from WEBENCH to TINA-TI/ALTIUM/PSPICE etc. You can find more details here.

    The unencrypted models wherever available, are really easy to import in TINA-TI and we have videos explaining step by step procedure for that too.

    I could import TPS70933 unencrypted model in TINA-TI without any issue and I have attached the generated macro here. 

    TPS70933_TRANS.TSM

    Hope this helps in your application. Please post on this forum if you face any issues with this or any other TI parts.

    Thanks!!

    Best Regards,

    Mahavir Jain.

    It will not compile: "Missing syntax element. Line # 88"  I'm running TINA Industrial V9.

    I'm sure you are doing your best but TI needs to devote far more resources to the job of producing device models. Encryption simply wastes everyone's time and resources. What are you protecting with encryption? If the same device is also offered without encryption haven't you defeated whatever that goal was?

    TI should offer a TINA model and a working circuit (.SCH) that can be opened and simulated. This .SCH contains a graphics symbol together with its macro (.TSM). These are the most important support items that you could offer, next to the data sheet. P-SPICE models are also important but not more so than for the simulation software that TI provides to its customers- TINA-TI.

    Take these suggestions up to Marketing. They are committing a grave error in not supporting some very fine new products. WEBENCH is not a replacement for TINA-TI!

    Neil,

    We will be releasing a new version of TINA-TI shortly (within the next month or so) which will take care of most netlist incompatibility issues with our unencryted models. Note that these enhancements may not be made to versions of TINA Industrial since that is controlled by Design Soft and not by TI.

    Also note that we are releasing the unencrypted models for many (not all) devices that we are now releasing. For models that were already released before we started this practice, we are releasing the unencrypted models as they are requested by customers and if they are approved to be released in that form by the business units.

    If you need any unencryted model, do let us know and we will provide it if that is approved.

    Thanks,

    Hi Neil,

    For now, please find attached the corrected macro file and TINA-TI schematic file for your application. Kindly note, this macro and schematic files are based on PSPICE unencrypted model file and project files.

    2402.TPS70933_TRANS.TSM

    TPS70933_TRANS.TSC

    Thanks!!
