TPS40304 time averaged spice model

Hi Ron,

Here is the link again for downloading SwitcherPro: www.ti.com/switcherpro

Best regards,

thanks for your response but I downloaded the switcherpro software a long time ago.

What I really need is a time averaged (state-space) spice model for this part that works in the TINA software. SPICE makes it possible to do a lot more analysis.

There are time averaged spice models available for other synchronous buck controllers. Why is there no time averaged model for the TPS40304?

The averaged models run so much faster than the transient models.

Hi Ron,

What features are you looking to test in the model? Yes, the state space average model does run faster than the transient model but you can get much more information from the transient model that you can not get from the Average Model (like switching behavior, ripple, current limit, etc).

Hi Nikhil,

I want to do small signal ac analysis. The transient conditions aren't required  for this type of analysis.

Hi Ron,

If you are just looking to do an ac analysis, then Switcherpro will give you the same loop stability information that you will get from a state space average model. Please find some snapshots below which shows the loop response. You can also change the compensation components to see how the loop response changes in the What if Analysis Tab.

Best regards,

Nikhil
