TPS62875-Q1: calculate and simulate gain and phase margin of TPS62875-Q1 and TPS62873Y1-Q1 tool

Hi Cynthia,

We can conduct AC analysis simulation to determine the gain and phase margins. Do you have Pspice apps? If not you can download Pspice for TI (free version) and install it to your computer including the model as well to perform the simulation. See the link below for reference.

Let me know if you need additional data.

Hello Excel,

I install Pspice but meet some questions about tool installation, i still in checking the reason. Maybe you can see it.

By the way, TI website without TPS62873-Q1 and TPS62875-Q1 Pspice model, you mean, for TPS62875-Q1, I can use TPS62874-Q1 Pspice model to simulate?? What about TPS62873-Q1?

Hi Cynthia,

For TPS62873-Q1, you can use the TPS62872-Q1 AC model, and TPS62874-Q1 for TPS62875-Q1 (refer to the links below). Both files are in Pspice models.

Just let me know if you encountered any issue with those models.
