Texas Instruments provides a recommended PCB layout in the TPS8268150SIPT datasheet, but it's also recommended to follow the 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 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 can also use online inductor selection tools or consult with an applications engineer for guidance.
The TPS8268150SIPT is rated for operation up to 85°C ambient temperature, but the maximum junction temperature is 125°C. It's recommended to derate the output current and ensure proper thermal management to ensure reliable operation at high temperatures.
Troubleshooting issues with the TPS8268150SIPT requires a systematic approach, starting with checking the PCB layout, component values, and input/output voltage levels. Texas Instruments provides a troubleshooting guide in the datasheet, and you can also consult with an applications engineer or use online resources for guidance.
The TPS8268150SIPT is an automotive-qualified device, but it's essential to review the specific requirements of your application and ensure that the device meets those requirements. You may need to perform additional testing and validation to ensure the device meets the required standards and specifications.
