“Regular readers of this blog will have already seen the article that I published about 4 months ago where I attempted to reverse engineer a voltage regulator module originally designed to fit into a Dell server. The theory was that these would be high quality, stable and robust designs that could prove useful if I could figure out how they worked. They’re certainly worth far more than the few pounds that you can get them for on ebay today. I was able to determine the function of the key pins on the module myself by experimentation and then with some help from eagle-eyed readers out there on the internet we were able to identify the module as an Artesyn NXA66 and subsequently a summary datasheet was located that provided the full pinout.”
