Universal AC Input: 10.5V/1.8A DC Output: Isolated Synchronous Flyback Converter Reference Design
Texas Instruments
The PMP10164 reference design supplies 10.5V@1.8A from universal AC mains; the isolated Flyback topology is the most used for low power range due to single magnetic component. Since the load is a power line communication chip: a fixed frequency modulation has been chosen. The controller LM5021 performs also pulse skip mode thus improving efficiency at light load. A synchronous rectification controller UCC24630 has been employed to increase the efficiency and the thermal performance.
