Introduction Today’s switch-mode power supplies (SMPS) are smaller, more efficient, and lower-cost than ever. The key to their performance is the power switch technologies at their heart – but how should designers choose the right material for this and find the best component to meet their needs? While silicon is the most widely-known constituent of semiconductors, a new group of wide bandgap (WBG) materials is increasingly finding its way into applications. One example is gallium nitride (

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

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
