I have developed a multi output buck converter using a Delfino in the control loop. Now I am trying to determine if it is a better solution to use a UCD3138 digital control IC instead. I have been all over TIs website and I am having difficulty determining the advantages/disadvantages of each. I think the UCD3138 does not allow for on the fly PID calculations where the TMS320 of course does. Is this a fair assumption? Can anyone provide a concise comparison or point me in the right direction. Thank you.
