Margin

Important:

It is recommended that designs that could be sensitive to the peak current described in this

section include the recommended Cext 2x22 µF and dimension the power supply with an

extra 20% margin with respect to the values provided in this section.

Thermal Considerations

Special attention needs to be given to thermal dissipation.

The outer layers of the host board must be covered in as many wide copper areas as possible, and those

must be stitched with evenly spaced ground vias. Care must be taken that no air gap exists along the

thermal path from the RYZ024A to the dissipating copper area(s). Gaps can be filled with heat conducting

materials such as GapPad™.

The Gxx pads should be tied to a large ground plane on the customer's PCB layer 1. It is also recommended

to have the Gxx pads area on the PCB stitched with through ground vias to improve thermal dissipation.

If the host board is piggybacked over a larger board, the aforementioned heat dissipation considerations

should be applied to both the main and the daughter board.
