Part Number: UCC28056
is there an LT-Spice model of UCC28056 available and if so could you please send it to my Mail Adress or answer with a link ?
Thank you very much.

In reply to Eric Faraci:
thank you for your quick reply. I will look into the SIMPLIS Model and try to create my System with it.
Would you have a suggestion of how to design my inductor if I want to use UCC28056 as a DC/DC - converter (Boost only, without PFC) ?
My current problem is that I am not entirely sure how the CrM/DCM Control Principle of UCC28056 works. I need to find an ideal frequency, so that I can determine the correct boost inductor needed to boost my minimum Voltage (210 VDC) to my 390 VDC output. The problem that I have is that UCC28056 can change both the frequency and also the ON-Time to regulate my output to 200 W at 390 VDC. I believe that UCC28056 only uses frequency modulation for PFC purpose and the ON-time will change to regulate output-power and voltage regulation purposes.
Could you tell me weather I am correct with my assumptions ? Also, would you have a suggestion for my switching frequency of UCC28056 so that I can design and determine the inductor needed for my application ?
