TPS54810PWPR datasheet by Texas Instruments

TPS54810PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54810PWPR?
  The maximum input voltage that can be applied to the TPS54810PWPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the TPS54810PWPR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10uF ceramic capacitor between the VIN and GND pins. Additionally, use a low-ESR output capacitor and keep the output voltage ripple below 1%.
• What is the minimum input capacitance required for the TPS54810PWPR?
  The minimum input capacitance required is 4.7uF, but it's recommended to use a 10uF or larger ceramic capacitor to ensure stability and optimal performance.
• Can I use the TPS54810PWPR in a high-temperature environment?
  The TPS54810PWPR 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 reliability and prevent thermal shutdown.
• How do I adjust the output voltage of the TPS54810PWPR?
  The output voltage of the TPS54810PWPR can be adjusted by using a resistor divider network between the VOUT and GND pins. The recommended resistor values are R1 = 10kΩ and R2 = 2.2kΩ for a 3.3V output, but you can calculate the values for your desired output voltage using the formula in the datasheet.
