m15981 Posted January 11, 2007 Report Share Posted January 11, 2007 Hi thereI am working on a project which requires two voltage inputs from an smps. Because my time is limited i don't have enough time to design and implement my own smps so i have decided to go with an open frame ready made one. The one i am planning to use is 5V, 8A output. Because i need two inputs to my circuit i want to modify the smps to output 5V at 1-2A and 3.15V with the rest of the current. Any ideas on how this can be done? Thank you Quote Link to comment Share on other sites More sharing options...

indulis Posted January 13, 2007 Report Share Posted January 13, 2007 ou could use a buck converter. Limiting the current for the 5V @ 1-2A could be an issue if you can't live with a fuse. Quote Link to comment Share on other sites More sharing options...
Fowkc Posted January 14, 2007 Report Share Posted January 14, 2007 You might want to look at the "5v to 3.3v" thread near this one. Basically deals with the same problem, but you'll need to account for the increased current your converter will be carrying. Quote Link to comment Share on other sites More sharing options...
