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 choice of inductor depends on the specific requirements of your application, including the output voltage, current, and frequency. TI provides a list of recommended inductors in the datasheet, but you may also need to consider factors such as inductor size, core material, and saturation current.
The TPS56520PWP is rated for operation from -40°C to 125°C, but the maximum ambient temperature range may be limited by the specific application and the components used. It's important to consider the thermal characteristics of the IC and the overall system design.
Yes, the TPS56520PWP is qualified for automotive and high-reliability applications, and meets the requirements of the AEC-Q100 standard. However, it's important to follow the specific requirements and guidelines for your application, and to consult with TI's technical support team if necessary.
TI provides a troubleshooting guide in the datasheet, which covers common issues and their solutions. Additionally, you can use tools such as oscilloscopes and current probes to debug the circuit, and consult with TI's technical support team if necessary.
