PCB Layout considerations To achieve optimal parameters for the DC/DC converter (e.g. efficiency or ripple voltage), attention has to be given to the PCB layout. Figure 3.23 shows the DC/DC converter, its external elements and two high frequency loops. The length of each loop has to be as short as possible. Furthermore, the distance between SW and FB has to be as large as possible to decrease the interference. It is recommended to have ground planes in between each signal line.
