Unless I am completly missing something and this is quite possible, there are a couple of things slightly confusing me at this point!
The first one is in datasheet: http://www.ti.com/lit/ds/symlink/tps54331.pdf Equation (13) what is the "D" referencing?
The second query i had was regarding crossover frequency. The same datasheet states "internal circuit limitations of the TPS54331 device limit the practical maximum crossover frequency to about 25 kHz" yet the evaluation board TPS54331EVM-232 datasheet shows the crossover around 90kHz
If there could be any clarafication on these 2 things, that would be sweet!
