Len Crane, Senior Technologist, Coilcraft

New power electronic developments are bringing the hazards of electrical energy closer to users than ever before. There are developing applications like electrified vehicles with 400 v or 800 v batteries, data centers with +/- 400 v racks, and faster switching devices with 650 v or higher ratings. These innova

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
