TPS650332-Q1: request helping the PSpice simulation for PMIC

Hello Phil Phil Yi

Thank you for your support.

I just followed the "Getting Started with the TPS65033x-Q1 PSpice Models" and I want to do simulation frequecny response

But I couldn't get any simulation result just as like yours

Here is my setting environment

can you please help me how to set up the tool and environment, let me know how draw the circuit as well.

Hi SEULKI,

   I don't have experience with the tool; I'm trying to ask our other members for help. I'll update here whenever I get any answers. 

Thanks!

Phil

I am also simulating the same circuit, but I am getting some errors while running the test files provided by TI in Pspice for TI tool.

Can u please let me know what I am missing..SEULKI KIM

Thanks and regards,

Sathish Raja C

Hi Sathish,

  I'm still waiting for answers from the expert of Pspice tool. I'll update you whenever I get answers. 

Thanks!

Phil

Do we have any answers for the error that we are getting in PSpice for TI tool when using the TPS6530 PSpice model.??

There are some critical deliverables ON-HOLD due to this.

Thanks,
Sathish

Hi Sathish,

  I got answer from our simulation expert copied and pasting below:

 The bode plot is complicated and time consuming to simulate in pspice. here's an example: https://www.ti.com/lit/pdf/sluaa51

 It's recommended to use Simplis for any simulations on the buck converters.

 PSPICE for TI has some restrictions on 3rd party models. fedora bucks are 3rd party since they were developed before PSPICE for TI was released. 

 It's recommended to use OrCAD simulator like SEULKI, or Simplis for buck related sims. LDO model is ok in PSPICE for TI

Thanks!

Phil

Hi Phil,

I am also using Orcad Capture CIS 24.1.But when I try to open the Pspice model it showing the below error.

Kindly provide your response ASAP.

Thanks,

Sathish

Hi Sathish,

I got answer from our simulation expert copied and pasting below:

   Did you make some modifications to the design in PSpice for TI and then try to reopen? You should start with the .dsn fresh from the zipped version on mySecure.

Thanks!

Phil

Hi Phil,

Yes..As persuggestion I just tried opening a fresh .dsn file. Now I am able to open the project.

But the Buck Subckt shows an error when Simulated. LDO circuit is running and plots are available.

Error Snapshot of "Buck1_1p5uH" subckt.:

Error:

.subckt one_shot in out

+ params:  t=1000
---------$
ERROR(ORPSIM-16361): Invalid parameter name

Configured Lib files in Simulation profile.

Kindly provide your response ASAP.

Thanks,

Sathish

Can we have a short call with Simulation expert in TI further to discuss on this issue. We need to resolve this issue ASAP.

Do schedule a call @9pm IST if possible.

Hi Phil,

Any update on the issue.

Kindly provide your reply ASAP.

Thanks,

Sathish

Hi Sathish,

  Just send you a WebEx meeting invitation on Thursday @9pm IST.

Thanks!
