Figure 1. WBG and silicon power switch Infineon brands positioning

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 (

Figure 1. Electrical schematic of bipolar, bidirectional, 2-terminal power supply: VIN = 5 V to 24 V, VOUT = ±10 V at 3 A

Most electronic systems depend on power voltage rails that are either positive or negative, but a few applications require individual rails that can be both. In these situations, positive or negative power is supplied by the same terminal—that is, the output voltage of the supply can be adjusted through its en
