Texas Instruments provides a recommended PCB layout in the TPS61122PW evaluation module documentation, which includes guidelines for component placement, trace routing, and thermal management to ensure optimal performance and minimize noise.
The selection of the inductor depends on the specific application requirements, such as the desired output voltage, current, and frequency. Texas Instruments provides an inductor selection guide in the TPS61122PW datasheet, which includes formulas and tables to help engineers choose the right inductor for their design.
While the datasheet specifies an operating junction temperature range of -40°C to 125°C, the maximum ambient temperature for reliable operation depends on the specific application and thermal management. As a general guideline, Texas Instruments recommends keeping the ambient temperature below 85°C to ensure reliable operation.
Texas Instruments provides a troubleshooting guide in the TPS61122PW datasheet, which includes common issues, possible causes, and recommended solutions. Additionally, engineers can use simulation tools, such as TI's WEBENCH Power Designer, to simulate and analyze their design before prototyping.
Yes, the TPS61122PW is qualified for automotive and high-reliability applications, and meets the requirements of the AEC-Q100 standard. However, engineers should ensure that their specific design meets the relevant industry standards and requirements, and should consult with Texas Instruments' technical support team for guidance on using the TPS61122PW in these applications.
