GaN FET Drivers
Gallium nitride (GaN) field-effect transistors (FETs) are disrupting the power conversion market and are displacing silicon-based metal–oxide–semiconductor field-effect transistors (MOSFETs). Compared to MOSFETs, GaN FETs operate much faster and have higher switching speeds in the smallest possible volume. The promise of GaN is that it can dramatically reduce the size and weight of any power supply. However, these high-performance GaN transistors need an optimized gate driver to reach their performance potential. More...
