Recommended PCB layout

The STOD13CM is a high frequency power switching device and therefore requires a proper

PCB layout in order to obtain the necessary stability and optimize line/load regulation and

output voltage ripple.

In order to minimize ground noise, a common ground node for power ground and a different

one for analog ground must be used. In the recommended layout, the AGND node is placed

by a separated layer routing on the bottom through vias.

The exposed pad is connected to AGND through vias.
