LM51770: PSpice Model

Would you be able to provide control loop and other internal information so I could make my own model?

Not even with an NDA? We've done that before. I'm not sure if there is one in force now but we would be happy to sign one.

Hi Anthony,

let me check and come back in a few days.

Would a Simplis model for you work as well?

Best regards,

Thanks Stefan. Ultimately, I need a PSpice model, but having a Simplis model would be great for verifying the PSpice model.

Let me clarify some things. We need to make a Pspice average and transient model for a customer that has requested a model for this part. We'll take all the data we can get, control loop, dynamic, output impedance, startup, etc. The datasheet alone is not sufficient. We may be able to get some data from the eval board but modeling the transition between buck and boost modes is an interesting challenge that we probably need some help with. My employer (AEI Systems) has signed NDAs with TI in the past. We actually had a 10-year collaboration where we made models for TI. We are ok to sign an NDA to get the data.

Hi Anthony,

We will not able to share details about the internal control logic beside what is provided in the datasheet.

We could support you with additional measurement results which has captured during validation - in addition to what is provided in the datasheet.

For sure for that an NDA would be required. So you might get in contact with your local TI support for that.

Best regards,

 Stefan

Okay, I will reach out to local TI support for the NDA. Are you able to give me the Simplis model for now without the NDA?
