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 selection of the inductor depends on the specific requirements of your design, such as the output current, switching frequency, and desired ripple current. Texas Instruments provides a list of recommended inductors in the datasheet, but you may also need to consider factors such as inductor core material, size, and saturation current.
The maximum ambient temperature for the LMR43620R5RPER is 85°C, but the device can operate up to 125°C junction temperature. It's important to ensure that the device is properly cooled and that the thermal design is adequate to prevent overheating.
The LMR43620R5RPER is an automotive-grade device, but it's still important to ensure that it meets the specific requirements of your application. You should review the device's AEC-Q100 qualification and PPAP documentation, and consult with Texas Instruments' support team if necessary.
Texas Instruments provides a troubleshooting guide in the datasheet, which covers common issues such as output voltage errors, oscillations, and overheating. You can also use tools such as oscilloscopes and thermal cameras to help diagnose problems, and consult with Texas Instruments' support team if necessary.
