That was a few years ago, a few of the new micro controller have suitable peripherals for power conversion. I am actually not sure FPGAs have DAC, ADC and fast comparators which are part of these suitable peripherals.
In some micro controllers it is not about horse power. Peripherals may handle the power conversion with slope generation and micro controller only intervene then adjustment are needed like adjusting peak current value. The micro controller may are however very useful for example to calculate temperatures or implementing a communication protocol, in practice application specific tasks. The power conversion topologies are still the same. I have done FPGA and they are very nice to work with then it come to timing of IO signals. Nicklas Karlsson > Depends on how you define suitable.
