LMG1025-Q1: LMG1025-Q1

Hi Muthugayathridevi,

The PSpice model (not TINA) for the LMG1025-Q1 should be unencrypted.

When you download the file, it will give you the LMG1020 model, but both devices are electrically the same. The biggest difference comes from the package, where the LMG1025-Q1 has leads, adding parasitic inductances. If you would like to simulate this, then you could add a ~1nH inductance in series with the pins, but it likely won't make a noticeable difference unless you are using very high switching frequency.

Thanks,
Rubas

Hi Muthugayathridevi,

Please read this FAQ to learn how you can tell a model is unencrypted: https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/692603/faq-tina-spice-how-do-i-know-if-a-model-on-ti-com-is-unencrypted

I used that to check if the LMG1020 model is unencrypted, but you can try it as well to learn.

Then, read this FAQ to learn how to import an unencrypted model into other Spice tools: 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

Thanks,
