The isolated AC-to-DC flyback converter is the most commonly used power supply type for home and industrial devices. Fear of the main voltage and complexity of calculations cause electronic beginners and enthusiasts to procrastinate DIY such circuits. This project introduces an AC-to-DC flyback switching power supply that converts universal 50Hz AC input (85V-260VAC) to 12VDC-0.5A (6W) using the minimum components in the BOM, both price and quantity.
