A correct printed circuit board (PCB) layout is one of the most important aspects to having a successful power supply design. Non-isolated power stages are the basic building blocks of power systems. Understanding where the currents are flowing and how the high-frequency loops are constructed is the most important step.
Port Problems: Data and Power
Blog 3/22/2016 2 comments
Engineers try to make maximum use of available resources and extend them to new uses. This true of data links such as USB and Ethernet: both were originally conceived as primarily for data, and their potential power-supply roles were secondary, if considered at all. But times change and needs evolve, and the yes data/no power thinking has turned as well.
