The next generation of wall chargers
Way back in the 90s aerospace was replacing silicon with gallium arsenide to make more efficient and faster chips.
I’m glad to see it’s finally reaching a useful commercial application.

Note that this is Gallium Nitride (GaN,) not Gallium Arsenide (GaAs).

Right but I believe it is a similar process built in the same R&D.

Had forgotten about that. I worked at the Rockwell science center at that time and went into their clean room once and had to put on a “bunny suit” to work on some computers inside it. They had a gallium chip product of some sort.
