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.

Hi Aishwarya,
You can modify the model available at https://www.ti.com/product/TPS62872-Q1#design-tools-simulation to evaluate these two parts as well.
Best regards

Hello,
I do not think there is Q100 that is direct replacement of this part. There is the TPS62872 this is a Low VIN device.
There is also a controller such as TPS5120-Q1, TPS51220A-Q1
thanks
