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 ...

Advanced semiconductor technology allows an increasing number of transistors to be integrated onto ever-smaller silicon chips. This increases the power density, however, and presents power-management ...

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 ...

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 ...
