TPS54910PWPR datasheet by Texas Instruments

TPS54910PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54910PWPR?
  The maximum input voltage that can be applied to the TPS54910PWPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the TPS54910PWPR 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.
• What is the minimum ESR required for the output capacitor?
  The minimum ESR required for the output capacitor is 10mΩ, but it's recommended to use a capacitor with an ESR of 5mΩ or lower for optimal performance.
• Can I use the TPS54910PWPR in a high-temperature environment?
  The TPS54910PWPR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability and prevent overheating.
• How do I calculate the output voltage of the TPS54910PWPR?
  The output voltage of the TPS54910PWPR can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
