Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important 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 output current, switching frequency, and output voltage ripple requirements. TI provides an inductor selection guide in the datasheet, and online tools such as the TI Inductor Selection Tool can also be used to find a suitable inductor.
The TPS65154RSLR has an operating junction temperature range of -40°C to 150°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system. TI recommends following the thermal design guidelines in the datasheet to ensure reliable operation.
Yes, the TPS65154RSLR is qualified for automotive and high-reliability applications, and meets the requirements of the AEC-Q100 standard. However, additional testing and validation may be required to ensure compliance with specific industry standards or regulations.
TI provides a troubleshooting guide in the datasheet, which covers common issues and their possible causes. Additionally, engineers can use tools such as oscilloscopes and thermal cameras to debug the issue, and consult with TI's technical support team for further assistance.
