Thank you for reply,
Customer is confirming UC3875, because customer require low switching frequency: 13kHz.
(Input: AC400V, Pout, 200W~50kW, Other spec: TBD)

Basically, customer question is why UC3875's web site describe UCC3895EVM-001.
If there any reason, please let me know.

Sorry for additional question for UC3875,
Is there equation for frequency (or Rt) setting? (UC3875 datasheet page-7)
