Long talked about, wide bandgap gallium nitride-on-silicon (GaN-on-Si) transistors are now commercially available. They are being touted for replacing silicon-based MOSFETs, which are turning out to be inefficient for many high-performance power supply designs. Recently, several suppliers of GaN-on-Si-based HEMTs and FETs have emerged in the marketplace, among them Efficient Power Conversion (EPC). To expedite the evaluation of eGAN FETs for power supply designs transitioning from silicon MOSFETs to eGaN FETs, EPC has released several development boards in the last few years.
