Want to build a multiple output PS, preferably with this chip. Unfortunately, having a road block finding it. 10 years out of production but was hoping someone knew of a reliable source. Lots of counterfeights out there. I found a discrete equalalent version someone created but kinda the last resort. If truly is not available, any suggestions? I want contstant voltage/current in the 50V / 5A range. I like the MC1466L since it is a floating regulator, limited only by pass elements.
