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 datasheet provides a list of recommended inductors, but you can also use the inductor selection guide provided by Texas Instruments or third-party inductor manufacturers. Consider factors such as inductance value, saturation current, and DC resistance when selecting an inductor.
The datasheet specifies an operating junction temperature range of -40°C to 150°C, but the maximum ambient temperature range depends on the specific application and thermal design. A general rule of thumb is to derate the ambient temperature by 10-20°C to ensure reliable operation.
Yes, the LM4671 is qualified for automotive and high-reliability applications. It meets the requirements of the AEC-Q100 standard for automotive-grade ICs and is also suitable for industrial and medical applications that require high reliability.
Texas Instruments provides a troubleshooting guide in the datasheet, which covers common issues and their solutions. Additionally, you can use oscilloscope measurements to analyze the switching waveforms and identify the root cause of the issue.
