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 input voltage, output voltage, and output current. Texas Instruments provides a list of recommended inductors in the datasheet, but you can also use online inductor selection tools or consult with an applications engineer to find the best inductor for your design.
The maximum ambient temperature that the LMR10515 can operate in is 85°C, but this can be derated based on the specific operating conditions and the thermal design of the system. It's recommended to consult the thermal design section of the datasheet and to perform thermal simulations to ensure that the device operates within its recommended temperature range.
Yes, the LMR10515 is qualified for automotive and high-reliability applications, and it meets the requirements of the AEC-Q100 standard. However, it's recommended to consult with an applications engineer to ensure that the device meets the specific requirements of your application, and to follow the recommended design and testing procedures to ensure the reliability and robustness of the system.
Troubleshooting issues with the LMR10515 requires a systematic approach, starting with a review of the PCB layout and the component selection. Check for any signs of oscillations or instability, such as ringing on the output voltage or excessive heat dissipation. Consult the datasheet and the application notes for guidance on troubleshooting and debugging techniques, and consider consulting with an applications engineer if the issue persists.
