Although I do not expect it, it would be interesting to see the schematic of your power supply design.

Although it is a completely different beast, there is a schematic for a software controlled DC-DC converter at http://www.ti.com/lit/ug/slau597/slau597.pdf page 36 - for the new MSP432 launchpad.

I pretty much gave up on switched mode power supply design many years ago when I found that the 25V EPROM programming voltage I generated had a 1 microsecond 14V overshoot that instantaneously killed my EPROMs.
