As I thought...completly dependent on the loads, how they come up, etc. The basis for this was from one of our software engineers who is controlling the power up of several power supplies, and wanted to minimize the sag/glitch from each supply, Right now there is a 1uS delay between and he wanted to attempt to minimize it. I figure, if it ain't broke, don't fix it! Else we need to put some power analysis gear on the lines to really look at things. Thanks for the feedback. _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
