LM51581-Q1: Please provide the unencrypted PSPICE transient model of LM51581-Q1

Part Number: LM51581-Q1
Other Parts Discussed in Thread: LM5158


We need to simulate the boost converter application using LM51581-Q1 and I could only find the encrypted PSPICE transient model of the same in TI's website. It's an immediate requirement to simulate and validate the performance of LM51581-Q1 in LTspice and to purchase this part in the next step. Please provide the unencrypted PSPICE transient model of LM51581-Q1.

Kindly consider this query ASAP.

  • Hi Naveen,

    Thanks for using the e2e forum.

    We can provide the unencrypted PSpice model for LM5158, which can then be transferred to other simulators like LTspice.
    This requires an NDA with Texas Instruments.

    If you already have an NDA, (or need to create one,) please get in touch with your FAE or marketing contact you created the NDA with, so they can request the unencrypted model which will then be sent to you within 1-2 days.

    We cannot share the unencrypted model directly via the forum.

    I am very sorry for this inconvenience.
    Best regards,
