LEDs have come a very long way in performance and “comfort factor” in the past few decades for many good reasons. At the same time, the basic ac-line LED “supply” consisting of an ac/dc voltage-output ...

One trend that shows no size of ending is the move to smaller personal electronic devices. From smartphones to tablets, each successive generation is smaller and more powerful than the last. It’s ...

Compared to conventional hard-switched converters with fixed switching frequencies, the quasi-resonant converter (QRC) topology is a very attractive alternative for power supply designers. The ...

ST’s VIPerGaN50W houses a 700-V GaN power transistor, flyback controller, and gate driver in a compact 5×6-mm QFN package. The quasi-resonant offline converter delivers up to 75 W from high-line input ...

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 ...

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 ...
