UCC28019A: Design help

Part Number: UCC28019A
Other Parts Discussed in Thread: UCC28019, UCC28180, UCC28070, PMP

Hello experts,

I wanted to verify my thought process with you.

I am planning to use UCC28019A to design a 600W DC-DC application. PFC followed by an LLC

input voltage: 80- 125VDC

Output voltage:12V after LLC and 390-410 VDC after PFC.

My question is since RMS value corresponds to DC (in a manner of speaking), Can I make do without the bridge rectifier?
