Hello Eric
For this, they would need two UCDs, one for AC/DC (PFC), and the other for DC-DC.

PFC controller would be on the primary side, and DC/DC controller on the secondary side.

We have a number of different topologies to choose from for the DC/DC, with reference firmware and EVMs / reference designs to support development. We also have an EVM and reference design for PFC.

See www.ti.com/.../toolssoftware for a list of our reference firmware, reference designs, app notes, design kits and EVMs.

Do they have a preference for topology for the DC/DC?

Best Regards
Cormac
