TPS281C100ADNTR Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency layout guidelines, such as keeping the input and output traces short and away from each other, using a solid ground plane, and minimizing vias and thermal reliefs.
To ensure stability, follow the datasheet's guidelines for output capacitance, input capacitance, and feedback resistors. Additionally, make sure the output voltage is within the recommended range, and the input voltage is within the specified operating range. You can also use the TI Power Stage Designer tool to help with stability analysis.
The maximum ambient temperature for the TPS281C100ADNTR is 85°C, but it's recommended to derate the device's power dissipation at higher temperatures to ensure reliability and prevent thermal shutdown.
The TPS281C100ADNTR is an industrial-grade device, but it's not specifically designed for high-reliability or automotive applications. For such applications, consider using devices with higher reliability ratings, such as the TPS281C100QDNTR or other automotive-grade devices from Texas Instruments.
Use an oscilloscope to measure the input and output voltages, as well as the switching node voltage. Check for proper PCB layout, component selection, and soldering. Consult the datasheet and application notes for troubleshooting guidelines, and consider using TI's Power Stage Designer tool to simulate and analyze the design.
