These tiny isolated DC to DC converters are amazing. When you think that they can withstand kV, some for minutes at a time, it's pretty impressive engineering, all in a tiny form-factor that still manages to be highly efficient and avoid over-heating. I'm amazed by the knowledge that goes into making these, all the various disciplines that need to work together to make these tiny devices...
