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 specific application requirements, such as the output current, switching frequency, and desired ripple current. TI provides a list of recommended inductors in the datasheet, but it's also recommended to consult with inductor manufacturers and use online tools to select the optimal inductor for the specific design.
The TPS650945A0RSKR has a maximum ambient operating temperature of 85°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
Yes, the TPS650945A0RSKR is qualified for automotive and high-reliability applications, and meets the requirements of the AEC-Q100 standard. However, it's recommended to consult with TI's automotive and high-reliability teams to ensure that the device meets the specific requirements of the application.
TI provides a troubleshooting guide in the datasheet, which includes steps to identify and resolve common issues. It's also recommended to use oscilloscopes and other diagnostic tools to measure the output voltage, current, and switching waveforms to identify the root cause of the issue.
