We know Efficient Power Conversion (EPC) has commercialized enhancement-mode GaN-on-Si FETs, or eGaN FETs as EPC calls them, for more than a year now. Concurrently, it has been working with partners to realize dedicated drivers for its eGaN FETs, which offer lower RDS(ON) at higher voltages, lower gate charge, and no reverse recovery loss (QRR)—all these properties from a smaller die size than silicon. In essence, by comparison to silicon MOSFETs, the eGaN FETs offer a dramatic reduction in figures of merit or FOM.
