It did work. You may want to look at Maxim et. al. for better controller chips nowadays, but the down side to all those is that you have to wind your own transformer. If anyone knows of an off-the-shelf transformer that mates well with one of these chips, I'd certainly like to hear about it. > I am trying to locate a 12 VDC to + - 15 vdc dc to dc converter.
