hi.....
this is for my mini project automatic stepup transformer..
need......
+5v for microcontroller
+12v for relay driver......
device have to work for a line voltage range...100v t0 250volts..
.
can any one suggest some circuit ideas for this requirement...
i know that some smps circuit will do... but i don't need that kind of load regulation..... just need the line regulation........![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
