TINA/Spice/TPS92515: Can the simulation PSpice model "TPS92515 PSpice Transient Model "work on 48v?

Terri Wang

Part Number: TPS92515
Other Parts Discussed in Thread: TINA-TI, , ,

Tool/software: TINA-TI or Spice Models

I am using this "TPS92515 PSpice Transient Model" downloaded from the TPS92515HV-Q1 tools and software page, I put Vin as 48V, after running the simulation for 5ms or 7ms, I will see a dip in the current for one of the LED channels, the V(U8:CSN) will also have a abnormal dip in the plot at the corresponding time. I wonder if this transient model can be running at the 48V Vin. Please see attachment for the waveform that we see. Do you guys have PSpice model for the TPS92515HV-Q1 itself?

Thanks,

Hi Terri ,

We are looking into this question and we let you know as soon as we verify the performance or the issue. Thanks for bringing it to our attention.

Kind Regards,

Terri,

There is PSPICE model and TINA model at the same location. Please visit the page and look again. Let me know if you still can not see the PSPICE model ( same model).

The dip that you see may be the result of simulator's calculation at that time and the tolerance used, noting abnormal.

I verified this with team and it is no issue. I am closing this thread but if you can not see the PSPICE model , you can reply to it .

Arash,

I saw this PSPICE model for the TPS92515, not the TPS92515HV. just want to make sure the model you put in there also includes the HV model. It is not the cause of dipping in the waveform.

Thanks,

Terri

Hi Terri,

Yes, Same model is used for both parts and working as expected.
