I think you could use DC-DC converter that outputs 5V. The dropout on the regulator used is 1.5V, and 3.3 + 1.5 = 4.8V. Not a lot of headroom but it should work OK.. Right? :) You could test it using your PC power supply before spending money too. Farnell sell DC/DC converters that will do the job but they are not cheap (>AU$100) http://au.farnell.com/jsp/Electrical/Power+Supplies+&+Converters/POWERBOX/PBBA-1205F/displayProduct.jsp?sku=3821067 They also sell DC/DC converters that will go down to 3.3V but then you would need to remove the existing regulator and it would almost certainly be much noisier without the linear regulator in there. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
