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 (

Slightly more than forty years ago, the silicon power MOSFET was a disruptive technology that displaced the bipolar transistor as the power conversion device of choice for the semiconductor industry – and a $12B market emerged.
