Part Number: UCC256301

Hi,

Two questions here:

1. Can UCC25630 support full bridge LLC driver?

2. If yes, is there any reference design? If not, then could you help to explain it?

Thank you.

We currently cannot support full bridge application as is. This is because in a full bridge application, the Vcr voltage be both positive and negative. The UCC25630x uses the Vcr voltage as part of its feedback loop. Hope this helps...
