Flyback Insights

What is Flyback?

A flyback converter is a type of isolated power supply that uses a transformer to provide galvanic isolation and step-up or step-down voltage conversion. It works by storing energy in the transformer's magnetic field during the switch's on-time and then releasing that energy to the output during the switch's off-time. Flyback converters are commonly used in low to medium power applications, such as AC adapters, battery chargers, and auxiliary power supplies.
