TPS54339EDDA datasheet by Texas Instruments

TPS54339EDDA Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54339EDDA?
  The maximum input voltage that can be applied to the TPS54339EDDA is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the TPS54339EDDA is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic input capacitor and a 22uF ceramic output capacitor. Also, keep the feedback loop as short as possible and avoid using long traces.
• What is the minimum input voltage required for the TPS54339EDDA to operate?
  The minimum input voltage required for the TPS54339EDDA to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
• Can I use the TPS54339EDDA in a high-temperature environment?
  The TPS54339EDDA is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation. Consult the datasheet for more information on thermal derating.
• How do I adjust the output voltage of the TPS54339EDDA?
  The output voltage of the TPS54339EDDA can be adjusted by changing the resistive divider ratio of the feedback resistors (RFBT and RFBG). Use the formula provided in the datasheet to calculate the required resistor values for the desired output voltage.
