PCB layout

The STOD02 is a switching device in which the PCB must be designed in line with switched

supplies design rules. The power tracks (or wires in the demo board) must be as short as

possible and of suitable width, because of the peak currents involved. It is recommended to

use a 2-layer PCB to attain the best performance. All external components must be placed

as close as possible to the STOD02. All high-energy switched loops should be as small as

possible to reduce EMI. Efficient cooling is needed and may be done by using a dedicated

copper area on the PCB.

possible to the PGND pin in order to create a good GND route.
