TPS92518PWPR Frequently Asked Questions (FAQs)

  • TI recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer to improve thermal performance. Additionally, keep the thermal vias as close as possible to the device and use a thermal pad on the bottom of the package.
  • Use the TPS92518 Configurator Tool provided by TI to generate a configuration file that meets your specific requirements. This tool helps you select the correct settings for your application, including output voltage, switching frequency, and current limit.
  • The TPS92518PWPR can handle input voltages up to 65V, but it's recommended to keep the input voltage below 60V to ensure reliable operation and minimize the risk of damage.
  • Use an oscilloscope to monitor the output voltage, input voltage, and switching node waveforms. Check for signs of oscillation, such as ringing or high-frequency noise. Ensure that the PCB layout is correct, and the input and output capacitors are properly selected and placed.
  • The device is rated for operation up to 150°C, but it's essential to consider the thermal derating and ensure that the junction temperature (TJ) does not exceed 150°C. Use thermal simulation tools or consult with a thermal expert to ensure the device can operate safely in your specific environment.
