Recommended PCB layout

The STOD03AS is 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 the 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

connected by a separated layer routing on the bottom through vias.

The exposed pad is connected to AGND through vias.
