Buck–boost converter - Wikipedia

WebFlyback converters have a number of advantages (potential simplicity because of the single switch, no output inductors required because the leakage inductance works for you, wide input voltage range), but those advantages mostly dominate at lower power levels. WebThe flyback topology is essentially the buck-boost topology that is isolated by using a transformer as the storage inductor. The transformer not only provides isolation, but by varying the turns ratio, the output voltage can be adjusted. Since a transformer is used, multiple outputs are possible.

Choosing A Converter or Regulator For your Power Supply Design

Webflyback converters need an elaborate compensation design for stability. This results in a tedious design process, bulky solution, with a higher component count and cost. An isolated buck converter (Fly-Buck) uses a synchronous buck converter with coupled inductor windings to create isolated outputs.
