9.4.2 Layout Example

An example layout, shown in Figure 9-5, is from the TMCS1133xEVM User's Guide. Device performance is targeted for thermal and magnetic characteristics of this layout, which provides optimal current flow from the terminal connectors to the device input pins while large copper planes enhance thermal performance.
