TPS650864: Kindly verify the below description for further reference.

Hi Jeevitha,

E2E threads are assigned to experts within specific product lines, so if you send a list of several unrelated devices in is not going to be seen by the expert for each device. Generally all available models for each device will be available in the ti.com product folder for that device. For example, the TPS650864 does not have an IBIS model: https://www.ti.com/product/TPS650864#design-tools-simulation 

The LM7310 has PSPICE models, but not IBIS: https://www.ti.com/product/LM7310#design-tools-simulation 

For the other devices you can do a similar check. 

Best regards,

Matt
