TPS54917RUVR Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
  • To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a small ceramic capacitor (around 10nF) between the VIN and GND pins.
  • The minimum input voltage is 2.7V, but it's recommended to keep it above 3.5V for optimal performance and to ensure the internal voltage regulator can operate correctly.
  • The TPS54917RUVR is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure proper heat dissipation to prevent overheating. A heat sink or thermal pad may be necessary for high-temperature applications.
  • The output voltage can be adjusted by changing the resistive divider ratio between the FB pin and the output voltage. Use the formula provided in the datasheet to calculate the required resistor values for the desired output voltage.
