I've been designing some circuits considering TI parts for LED Illumination. The following ICs are of interest for a 75W Street Light, with Boost PFC, LLC, and Buck stages:
- ucc28810 http://www.ti.com/product/ucc28810
- tps92020 http://www.ti.com/product/tps92020
- tps92641 http://www.ti.com/product/tps92641
Simulating the complex switching and interaction of these has not been possible yet. Are there SPICE or SIMPLIS models available for any of these models? Any simulation program would do. It would be an immense help for the project to be able to confirm current designs work properly.
Best Regards,
