1250 V/1700 V GaN HEMTs for NVIDIA 800 VDC Architecture

Kamal Varadarajan & Chris Lee, Power Integrations

GaN-based power semiconductors are ideal for high-efficiency power converters thanks to their superior material properties. However, very few manufacturers offer GaN HEMTs rated above 650 V. The main challenge is that GaN devices built on silicon substrates require very thick buffer layers, which adds significant pr
