Hi, TI support member

I want to simulate TPS53647 and CSD95372 with SIMPLIS.

But I could only find models for Pspice on TI's website.

Can I use this to SIMPLIS simulation?

Best, regards.

Hi, Yihe

Thank you for youre reply.　I got it.

Let me ask an additional question.

Can I control CSD95377Q4M with TPS53647?

If so, how should I handle the CSP and TSEN pins of the TPS53647?

Best regards.

Hi, Yihe

Thank you for reply.

I checked the reference design, but my questions remain unanswered.

CSD95377Q4 does not have TAO and IOUT.
This differs from the reference circuit(The difference between CSD95377Q4 and CSD95372BQ5M).

I've said it once, How should I handle the CSP and TSEN pins of the TPS53647?

Best regards.

You can follow below to connect CSP(ISP1 and ISN1)

As for TSEN, you can have a fixed voltage on this pin to report constant temperature but obvious you won't have the temperature sensing feature from the power stage.

But why not jus use CSD95372 so that you do not need worry all these.

Hi, Yihe

>But why not jus use CSD95372 so that you do not need worry all these.
CSD95372 is too large to fit on the board I am designing.
Therefore, I am considering using CSD95377.

Best regards.
