Looking for T2 Transformer details ... BOM and Schematic do not have any details.
Also "Excel Design Tool" for this design will help.
Hi Ramar,
The UCC2891 is designed for active-clamp forward topologies. In the table below, ACF topology is typically used to ~400W.
It's probably best to use a half-bridge or phase-shifted full-bridge topology.
Here are two reference designs that…
