2013-12-12 10:18 I have built this test circuit for the MC34063 switch regulator input 10 to 40V, output 5V 300mA, the MC34063 is the cheapest switch regulate available, you can get it for under 1kr. all others cost about 10kr. The circuit works very well.

i can only blink with a LED. I'm fighting with a problem the I/O IC
goes in to sleep mode and i can´t wake it. (I have fixed it☺)
I'm still not sure that it is the right device for the job.
