Has any one tested UCC25600 Pspice transient model? The TINA-TI transient spice model works, but somehow I could not get any gate drive signals from the Pspice transient model starting with the soft start phase.

FYI, We'll take a look at this.

Hi,

I downloaded the PSPICE model from Web and the model is switching. Please find the results obtained below:

The gate drive signals from the device (GD1 and GD2) are also probed and switching. Could you please elaborate on what you mean by "I could not get any gate drive signals from the Pspice transient model"

Regards,

Karthik

Thank you Karthik. Good to know it works. I will re-download and give it another try.

I restarted a new project and made the library configuration files only include ucc25600_trans.lib and nom.lib. Then this new project works fine. My previous project had a bunch of libraries configured and they may have interfered with the TI library. Thank you all for the help.
