TPS40200: Transient Spice Model and DCM question

Hi Fabian,

The PSPICE AVG model is available here: https://www.ti.com/product/TPS40200#design-development##design-tools-simulation. However, I don't see the PSPICE transient model here. Maybe you can use the TINA transient model instead - it's also located in the TPS40200 product folder.

Note that the example in that section of the datasheet referred to maintaining CCM operation at the light-load condition. Given that this is a non-synchronous controller, it will operate in DCM by default once the inductor current reaches zero.

Tim

Dear Tim,

Thanks for your reply.

There is an PSPICE transient model available (SLVM070.ZIP). However, it does not work with other SPICE simulators such as Micro-Cap, as it is encrypted. Also the TINA transient model does not work. 
Would it be a bad idea if you could check internal if the PSICE tranisient model version (SLVM070.ZIP) is also available as unecrypted version?

Thanks,

Fabian

Hi Fabian,

I suspect it is not available. Why do you need it unencrypted?

Tim

Hi Tim!

Unfortunately the encrypted transient model only works in PSpice. When using other spice simulators, the model has to be unecrypted. I am using Micro-Cap and the encrypted model does not work. I did run it in TINA but there my compinent library is not available ;) In case you find the unecrypted version, I would appreciate if you could share it over email.
