UCC28951: Reference design for high output voltage solution (over 2kW)

Guru 18390 points
Part Number: UCC28951
Other Parts Discussed in Thread: UCC28070, , UCC28950, UCC28070A

One customer is looking for Full-Bridge TI-Design, required spec is below;

・Input: 385VDC from UCC28070 (375V ~ 395V)

・Output: 140V / 15.3A (2142W) ~ 21.4A (3000W)

I looking for Full-Bridge TI-Design based on UCC28951 or UCC28950 solution, but I didn't find high Vout design.

Is there matched or near design? (Customer request is schematic and efficiency data)

If there Reference design for combination with UCC28070 or UCC28070A (PFC), it is the best solution.  

By the way, I found PFC design (spec is below); PMP4259, PMP4311, and Webench report. 

・Input: 198VAC ~ 264VAC (200V) 

・Output: 385VDC (375V ~ 395V) / 5.56A (2142W) ~ 7.89A (3000W)

Best regards,
