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, using a solid ground plane, and minimizing trace lengths and widths.
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 for guidance.
The maximum ambient temperature that the LMR51635XDDCR can operate in is 125°C, but this can be derated based on the specific application and operating conditions. It's recommended to consult the datasheet and thermal design guidelines for more information.
Yes, the LMR51635XDDCR is qualified for automotive and high-reliability applications, and meets the requirements of the AEC-Q100 standard. However, it's recommended to consult with an applications engineer and review the device's qualification data to ensure it meets the specific requirements of your application.
Troubleshooting issues with the LMR51635XDDCR typically involves checking the PCB layout, component selection, and operating conditions. Texas Instruments provides a troubleshooting guide in the datasheet, and applications engineers are also available to provide guidance and support.
