A common question comes up among power-management design engineers these days: “Is it time to switch from silicon power switches to GaN-based ones? Gallium-nitride (GaN) technology offers many advantages over traditional silicon-based MOSFETs. As a wide-bandgap semiconductor, GaN allows power switches to operate at high temperatures and achieve high power density. 

Due to its high breakdown voltage, GaN is suitable for applications above 100 V. Even below 100 V, its high power density and fast switching capability provide benefits like higher power-conversion efficiency in various power-supply designs.
