Efficiency should be a major consideration when designing a flyback switching power supply. It can impact many aspects of a product design from enclosure size and ventilation to safety qualification.

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

Several switching-converter topologies exist for power converters that operate from the ac mains and must maintain a power factor of 0.9 or better. One topology is a boost converter with a control ...

In PoE systems, performance of the flyback converter used to step down the 48-V supply in the powered device depends on careful transformer design. A growing number of electronic devices require both ...

Silanna Semiconductor has designed an active clamp fly-back controller to reduce the operational, no-load and stand-by power consumption chargers and adapters. Called SZ1131, it has an integrated ...

Designers can zero in on specific components that are more likely to generate noise and choose the best strategy that resolves the specific problem. While switch-mode power supplies operate at ...
