L´Episcopo Rating: N/A Votes: 0 Posted on Saturday, January 01, 2005 - 04:39 pm:    Henry: it is possible to build a simple and almost inexpensive power supply that can go down as low as 1,25V at a maximum current of up to 5 A (with a suitable heat sink)using an IC manufactured by National Semiconductor, the LM 338 K. The schematics can be found in the website of NS and it would cost about USD 60 / 80 including stepdown transformer and a suitable cabinet. Just take a look at www.nsc.com where the data sheet of the IC can be found. A technician would charge something to the parts cost for assembly of the parts and give also some kind of warranty. Need more help? just email me!. Besides, I wish you all a nice and good 2005!
