LM5156: does not work for a boost converter in LTSpice XVII after

Hi Guillermo,

thank you for using the E2E forum.

As LTSPice is not a TI tool we cannot give support for that.

You may use the PSpice for TI where this model have also be tested on.

PSPICE-FOR-TI Simulation tool | TI.com

But a question on that: why have you removed the } - can you not put it back again?

Best regards,

 Stefan

Hi Stefan, thank you for reply me

there was a syntax error on the ibrary itself. More precisely, the additional  } was after { 5u*V(U8_UVLO_OK)}.

Am I right? 

Hi Guillermo,

let me check with the PSpice library expert.

Best regards,

 Stefan

Hi Stefan,

thank you both, I hope you can solve my affair :) 

Hello Guillermo,

Like Stefan already mentioned, our support with other simulation software like LTSpice is very limited.

I can recommend you to look at this e2e thread:
https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/692613/faq-tina-spice-note-about-encrypted-models-and-importing-models-from-one-simulator-to-another

It describes some common errors when importing unencrypted PSpice libraries to other simulators.
I hope this can help you in debugging your simulation.

Please let me know if you have additional questions.
Best regards,
Niklas
