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.
Analog input (V
at the C
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
is placed close to C
connected by a separated layer routing on the bottom through vias.
The exposed pad is connected to AGND through vias.
