LM5045: LM5045 pSpice simulation creating errors

Hans

Part Number: LM5045
Other Parts Discussed in Thread: LM258, TINA-TI

Hello Team,

after downloading https://www.ti.com/lit/zip/snvm006 I tried to run a transient simulation. I see errors regarding LM258 and PS2501 like "ERROR(ORPSIM-15108): Subcircuit PS2501 used by X_U8_ext1 is undefined".

Can you help, please?

Thanks and Best Regards,

Hans

    Hi,

    It looks there are two issues because of the model was created by the National. (1) LM258 and PS2501 need to replace with existing TI parts as these two parts are not available from the existing model. (2) Even if these are replaced with TI current parts, the model still shows other vendors parts which would need to replace as well as the PSpice for TI only allows total three traces for non TI parts.  

    These replacement work is not trivial and we do not have resource to help the replacement work so at moment we can only provide the above suggestions.

    Hi,

    You may use the TINA-TI model for your simulation which should serve your simulation need. Somehow I cannot attach that file here. If you provide your email, I can send it to you.
