Boards in 2 GitHub repositories, designed in KiCad, that use the TOP227YN by POWER INTEGRATIONS (-40℃~+150℃@(Tj) 100kHz 67% 700V Boost、Flyback、Buck、Forward CCM、DCM Isolation Over Current Protection、Over Temperature Protection TO-220 AC-DC Controllers and Regulators ROHS). See how each wires it, with its parts, size, README and files; the TOP227YN’s symbol, footprint and pinout are on its own page.
Hirusha785/12V-5A-Isolated-Flyback-SMPS-KiCad
⚡ A 60W isolated flyback SMPS PCB design created in KiCad, converting 220V AC mains input to regulated 12V DC 5A output using TOP227YN, TL431, PC817 feedback isolation, and ER34 transformer topology.
