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, output voltage, and switching frequency. 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 TPS6521835RSLT has an operating junction temperature range of -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system. It's recommended to follow the thermal design guidelines in the datasheet and to perform thermal simulations to ensure the device operates within its specified temperature range.
Yes, the TPS6521835RSLT is qualified for automotive and high-reliability applications. It meets the requirements of the AEC-Q100 standard for automotive applications, and it's also suitable for industrial and medical applications that require high reliability.
TI provides a troubleshooting guide in the datasheet, which covers common issues and their solutions. Additionally, engineers can use tools such as oscilloscopes and thermal cameras to debug the issue, and can also consult with TI's technical support team for further assistance.
