PSpice import into ADS

Part Number: TLV1704-SEP
Other Parts Discussed in Thread: TL431

Tool/software:

Hello,

I am trying to import a PSpice model of the device into ADS from Keysight, but the circuit behavior does not look proper.
May you please support me to fix or adjust PSpice model, or maybe I am doing wrong something else?

I was able to import other TI components into ADS, for example TL431. With other SEP DC/DC converter I also had problem in the past, ADS support had to fix the model for me.

This is simple simulation I want to perform to make sure the model was imported correctly:


I expect, that when IN- (Blue) exceeds IN+(Red), output should go to the ground (Pink), but it does not happen:

During simulation I am getting these warnings:

Thank you in advance, looking forward to using your space portfolio in our satellite.

Best Regards,
