Texas Instruments provides a recommended PCB layout in the application note SLUA364, which includes guidelines for component placement, trace routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The selection of input and output capacitors depends on the specific application requirements, such as voltage rating, capacitance value, and ESR. TI recommends using low-ESR capacitors with a voltage rating of at least 2x the maximum input voltage. A minimum capacitance value of 10uF is recommended for the input capacitor, and 22uF for the output capacitor.
The UCC2917DTR is rated for operation from -40°C to 125°C ambient temperature range. However, the device's performance and reliability may be affected at extreme temperatures, and additional thermal management may be required for high-temperature applications.
Yes, the UCC2917DTR is qualified for automotive and high-reliability applications. It meets the requirements of AEC-Q100 and is manufactured using automotive-grade processes. However, additional testing and validation may be required for specific applications.
TI provides a troubleshooting guide in the application note SLUA365, which covers common issues and their solutions, including oscillation, instability, and overvoltage protection. Additionally, the guide provides tips for debugging and optimizing the design.
