Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines 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 output current, switching frequency, and output voltage. Texas Instruments provides a list of recommended inductors in the datasheet, but you can also use online inductor selection tools or consult with an inductor manufacturer to find the right one for your application.
The TPS65138ADRCR can operate in an ambient temperature range of -40°C to 85°C, but the junction temperature should not exceed 125°C. You should ensure that the device is properly cooled and that the thermal design is adequate for your application.
Yes, the TPS65138ADRCR is qualified for automotive and high-reliability applications, and it meets the requirements of the AEC-Q100 standard. However, you should ensure that your design meets the specific requirements of your application, including any necessary testing and validation.
Texas Instruments provides a troubleshooting guide in the datasheet, which includes common issues and their solutions. You can also use oscilloscopes and other diagnostic tools to identify the root cause of the issue, and consult with Texas Instruments' technical support team if needed.
