Is DC-DC much better than AC-DC? IIRC, DC-DC conversion typically uses a switched-mode power supply (buck or boost) that's from 60-95% efficient, or a 3-terminal regulator that's not so efficient, or a zener diode which is terribly inefficient. Perhaps this is going off topic, sorry. -- Charles Polisher _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
