XDPL8218’s IC parameters are configurable digitally via its UART interface, using Infineon’s user-friendly
Graphical User Interface (GUI) on a PC. This enables a lower Bill of Materials (BOM) and rapid engineering
changes without the need for complex component design iterations.
Note: By default, the configurable parameters of a new XDPL8218 chip from Infineon are empty, so it is
necessary to configure them before any application testing.
Figure 2 shows the XDPL8218 design guide document sectioning for each step of the recommended design
flow.
