Layout

The EVAL-M7-D112T board consists of two copper PCB layers. The copper thickness is 35 μm and the board's
size is 70 mm x 51 mm. The board material is FR4 grade with 1.6 mm thickness. Check Infineon's website or
contact Infineon's technical support team for detailed information. The Gerber files are available in the
download section on the homepage of Infineon's website. Login credentials are required to download these
files.
The layout of the top and bottom layers of the PCB are shown in Figure 10 and Figure 11. On the PCB layout,
users should place the decoupling capacitors as close as possible to the input pins, especially for current
feedback sensing and bus voltage sensing input decoupling capacitors.
