This slide shows an example of how digital control can be used to improve total system performance. In this case, a digital Barracuda bus converter is used to convert 48V down to a bus voltage that is then used to power several DLynx POLs down the line. The classic question in this case is “what is the best bus voltage”? The Barracuda Bus is capable of reading the bus current and setting the bus voltage, allowing for a range of potential answers.
