Yes, but only if you give more of the tiny details like how much current, whether isolated from the mains, how big, how accurate, what components do you have already, etc. etc. Regards, SJH Canberra, Australia

If you mean without using a transformer then Microchip (this is the PICLIST after all) has a technical brief that explains how to build transformerless supplies here: http://www.microchip2.com/lit/appnote/91008a.pdf David -- http://www.man.ac.uk/~mbhstdj
