I am an electrical engineer involved in the Power Electronics field for many years. I am new to this site. Does anyone know where I can find an LTSpice model for the UC1843A PWM IC? Any help would be greatly appreciated.
That looks like the unencrypted PSpice model that I had already downloaded from the TI site. I was under the impression that the syntax was different between the two simulators. Is this a model you have successfully run in LTSpice? Thanks for any help!
Here is a version of the TI UC1843A model modified for LTspice. I was downloaded from the TI website.
I only fixed the error(s) messages and didn't focus on the accuracy of the model. I would verify its behavior
before using it.
