Universal AC Input: 10.5V/1.8A DC Output: Isolated Synchronous Flyback Converter Reference Design

Description

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.

Features
  • LM5021 based Isolated Flyback in constant switching frequency delivering 10.5V@1.8A>87% efficiency at full load and 230VacSynchronous rectification with UCC24630 improves efficiency and thermal performanceOutput overvoltage protection with latch: in case of loop opto failThis design is tested and includes test results and CAD files
