I am currently using a MAX788 in my prototype ATX DC-DC PSU. I should have the first supply up and running this weekend. I received the final parts needed to complete it yesterday. Once it's built, tested, and running, I'll let you know how things went. After that I plan to have professional PCBs etched & drilled. Check my website for more info in a few weeks.
