LM5122-BOOST-CALC: Is it the case that the simulation model of LM5122 cannot be used in Simplis?

LIAO HAOCHENG

Part Number: LM5122-BOOST-CALC
Other Parts Discussed in Thread: LM5122, LM5045, PSPICE-FOR-TI

I downloaded the Pspice model of LM5122 from the TI website, but in Simplis, it shows that only Simetrix is supported.

At the same time, I also downloaded the model of LM5045. After adding the mold core, when I turned it on, there was no GND pin. Is this because of software incompatibility?

Hi，

Are you using the free version of SIMPLIS (SIMPLIS elements)? This has a limit of the size of the circuit you can simulate so it is not guaranteed to work with our models.

We do not have a SIMPLIS model for the LM5122,

You can use the models in "Design and Development" - "Design Tools and Simulations" on our product page and TI's simulation software (such as PSPICE-FOR-TI) for simulation.
