Jasper, I didn't use any fancy switching power supply knowledge - in fact, I copied the switching power supply schematic straight out of the LT1308 data sheet!
The clever part was figuring out that I could do things with the feedback resistor network to achieve current regulation and blanking voltage control. The power supply adjusts the output voltage as needed to make 1.2V appear at the feedback node. The rest is just simple resistor networks, as taught in any intro to electronics class.
