Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general best practices for switching regulator layout, such as keeping the input and output capacitors close to the IC, and using a solid ground plane to reduce noise and EMI.
The datasheet provides a list of recommended inductors, but you can also use the inductor selection guide provided by Texas Instruments to find a suitable inductor based on your specific requirements. Consider factors such as inductance value, DC resistance, and saturation current.
The datasheet specifies an operating junction temperature range of -40°C to 150°C, but the maximum ambient temperature depends on the specific application and cooling conditions. As a general rule, it's recommended to derate the regulator's power dissipation at higher ambient temperatures to ensure reliable operation.
The LMR43620MB5RPER is an automotive-grade device, but it's still important to review the datasheet and application notes to ensure it meets the specific requirements of your application. Additionally, consider factors such as fault tolerance, redundancy, and testing requirements for high-reliability applications.
Texas Instruments provides a troubleshooting guide in the datasheet, which covers common issues and their solutions. Additionally, you can use tools such as oscilloscopes and spectrum analyzers to debug the regulator's operation and identify the root cause of any issues.
