SIMetrix/SIMPLIS-compatible PSpice model for UCC28950.

Other Parts Discussed in Thread: UCC28950, UCC28C43

I am currently trying to simulate a phase-shifted full bridge converter using UCC28950 in SIMetrix/SIMPLIS but the PSpice model does not work in SIMetrix/SIMPLIS. I suspect that this is the case because the .lib file is encrypted. I wonder if TI provides an unencrypted model so that it can directly be imported to SIMetrix/SIMPLIS library. If not, can anybody help me simulate the UCC28950 in SIMetrix/SIMPLIS in other ways?

Hi Kenneth,

Yes, you are correct. The model is encrypted so you will need the unencrypted model to import into other simulators. Please refer to this FAQ for more details. However, although this is not generally the norm at TI, you are in luck since someone has already developed the SIMPLIS model for UCC28950. Please see below.
