Topology | Flyback Converter |
Input voltage | 332-459 V |
Output 1 | 23 V / 1 A |
IC revision | 1 |
This reference design uses the UCC28742 flyback controller to generate two outputs (23 V at 1.0 A, 5.0 V at 0.15 A) from a 3-phase input. The UCC28742 uses an optical coupler to regulate the output and to improve transient response. The valley-switching technique reduces switching losses and keeps the efficiency high
