Nope. I think SMPS's will go the way of disc drive and motor controllers and go all digital. And I don't see why you need a high power DSP for that since the feedback loop frequencies are typically on the low side. See this, for example. But time will tell...............................
Not only that, but the DSP board actually came with some code that could just be loaded in and it would work (control the 5w smps) ...but even though it was just a 5w buck converter, the dsp ran so hot that you couldn't touch it!!!......indeed software controlled smps feedback loops are pie in the sky..do you agree?
