11.2.1 Component Placement

The recommended placement is to have the TPS65982BB on the Top Layer and have all of the passive components on the opposite layer of the PCB. This will significantly reduce solution size and allows for more clearance for the high speed and interface signals. The figures below show the top and bottom placement.
