UCC25640EVM-020: Condition about AC input voltage with no PFC

Guru 17890 points
Part Number: UCC25640EVM-020
Other Parts Discussed in Thread: UCC256402, UCC256404

I considering UCC256402 and UCC256404, unused PFC condition. (Low output power)

Can UCC25640x use AC 85V~265V input without PFC?

I think that LLC condition is narrow Vin range, please let me know if there any difficult point of AC 85V~265V range.

Best regards,

Satoshi
