Specify current ripple ratio to optimize a power supply , relying on extrapolation rather than intuition to choose the right off-the-shelf inductor for your application. An inductor is designed for ...

Until recently, cost and the ability of a part to function in an application have driven the choice of inductors in desktop-computing systems' processor-voltage regulators. Designers have not been ...

VRMs (voltage-regulation modules) that power the latest generations of computer CPUs have historically used multiphase, interleaved buck converters. These VRMs must meet the tight Pentium 4 and Athlon ...

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 ...

Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...

Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...
