Molded Power Inductors

By: Carlos Farnos, Dr.-Ing. Efrain Bernal / Editor: Gerhard Stelzer, Würth Elektronik eiSos GmbH & Co. KG

Higher power requirements and miniaturization expose passives to rising temperatures, increasing the probability of thermal aging. This article explores how to select molded high-current power inductors, which are exposed to high temperatures for an extended time. The constant market demand to increase power density

Surge Current Limitations

Thomas Hunger, Oliver Schilling, Frank Wolter, Thomas Schütze Infineon Technologies AG Warstein, Germany

The ability of silicon power diodes to withstand a rapid forward current load, described by its i2t-value, is an important criterion that has to be regarded in the selection of the proper devices

Digital POL Power

Dan Tooth PhD, Field Applications Engineer, Texas Instruments

An engineer designing with FPGAs or Processors often has to provide some serious amount of power at high efficiency over load. Not only must the rails be regulated correctly and not overheat, but additional functionality may be required. Recent evaluation boards from Xilinx (ML605 and SP605) for Virtex-6 and Spart
