LTSpice Model

RussK on Mar 6, 2025

Category: Hardware

Product Number: LTM2882

Hello,

Does ADI have an LTSpice model available for the LTM2882, or another part which has similar functionality for port isolation? Specifically interested in modeling the internal isolated DC/DC converter function and its interaction with input impedance (ferrite bead filters) on the input supply voltage in terms of EMC performance - conducted and radiated.

Thank you.

Hi RussK ,

I don't see an available model for this part. I can ask around to see if anything with similar functionality is modeled.

Hi RussK ,

There is this article that shows the rough structure, and some info on EMC.

Also, the LTM2881 has an available IBIS model, though, not sure if that would really help you with EMC.
