UCC28056EVM-296: THD and PFC

Part Number: UCC28056EVM-296
Other Parts Discussed in Thread: UCC28056

UCC28056 can not meet the  spec that customer required. It is tough for UCC28056 to meet THD1 and THD4, especially at 90Vac input.

If customer can lower their spec, for example ,THD1:15%,THD4:60%, you can suggest customer to use it.
