Part Number: UCC256304
Tool/software: TINA-TI or Spice Models
Please can I have a SPICE model for this component to aid in the design of a power supply? The only model that I can find is an encrypted SIMPLIS model and I am unable to use it because the free version of SIMPLIS does not support use of encrypted models. (SIMPLIS is not part of our standard suite of software and we do not design enough power supplies to warrant purchasing it. We always design with SPICE and we have always obtained sufficient results using SPICE and it is an environment in which our development engineers are comfortable. Therefore we have no interest in purchasing SIMPLIS. If no SPICE model is available, the free version would be an option - but the encrypted models do not work in the free version) Now I am left without any way to model the circuit... Please help... How can I model my power supply for which I would like to use TI's UCC256304 as the controller?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Arash Loloee:
My sincerest gratitude for your comprehensive reply. There are usually issues with the company that I work for insisting that their NDA be used while TI would probably insist that their NDA be used - deadlock. I appreciate your suggestion of using a SPICE model for a similar part - please could you recommend such a model? Even if I could simply model the core functionality (frequency control) of the LLC switcher (without all the other specialised features offered by the UCC256304) I would be happy. This would give me confidence in the design of my transformer, resonant inductor, choice of switches, caps, etc.
Thanks so much!
Please provide a SPICE model for a similar/equivalent LLC controller that I would be able to use to test the core functionality (i.e. voltages,currents & power for the isolation transformer, resonant inductor, primary and secondary hold-up capacitors, secondary rectifiers, MOSFETs) in SPICE of a circuit based on the Texas Instruments UCC256304. I understand that you will not provide a SPICE model for UCC256304. Please do provide a SPICE model for a another similar LLC controller that would generate the switching signals for the FETs and control the feedback in a way similar to UCC256304 so that I can evaluate the core functionality of my LLC ciruit.
In reply to Brendon Bentley:
While I develop models for devices, I can not comment on which I.C. is the best alternative for your case.
There are many controllers on TI website. Many of those have encrypted PSPICE models. You can see if those work for you. In general , I would search the site for parts of interest with specific keyboards ( controller, Flyback, and....) then from those you can see which are close to what you need and whether or not they have PSPICE model ( even though most probably their models are encrypted)
I hope this helps you to find the part that you are looking for. I am closing this thread but if you have any question you can reply back.
