The synchronous buck converter is a widely used topology in low-voltage, high-current applications. One common application is a point-of-load (POL) converter that transforms a system bus voltage of 48 ...

Basics of an isolated buck converter. Key specifications to consider in transformer selection. Steps involved in choosing the right transformer. Energy is transmitted to secondary coil only in T OFF ...

Today's feature-laden portable electronics devices, typically running off a single Lithium-ion cell, often use one or more step-down DC/DC converters to power the core processor or other key functions ...

Designing an “optimum” DC-DC converter always involves tradeoffs between cost, size, efficiency, and other parameters. For today's systems, efficiency is often the key performance metric because of ...

Another lifetime ago, and as a young engineer, I had to design a power conversion system. The input power came as raw electrical energy from a jet engine during flight. The output power was input to ...

Designing a circuit is a lot easier on paper, where components have well-defined values, or lacking that, at least well-defined tolerances. Unfortunately, even keeping percentage tolerances in mind ...
