The single stage PFC flyback converter remains the topology of choice in many off line AC-DC LED power supplies. This is largely due to its low component count and cost, combined with efficiency of ...

The choice between a flyback or single-ended primary inductance converter (SEPIC) topology often ends with the designer choosing the most familiar one, but that’s not always the right option, say John ...

In some circuits, galvanic isolation is necessary due to safety considerations. In other circuits, functional isolation is used to block any interference on signals. A galvanically isolated power ...

Which topology do you chose when your specification calls for a non-isolated power supply and the output voltage falls between the minimum and maximum input voltage? Is the tried-and-true flyback used ...

The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...

The Forward and Flyback converters are two popular topologies widely used in isolated DC-DC power converters. These topologies are favored by designers for their simplicity, ability to handle multiple ...
