TPS54973PWPR datasheet by Texas Instruments

TPS54973PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54973PWPR?
  The maximum input voltage that can be applied to the TPS54973PWPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the TPS54973PWPR 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. Also, keep the output capacitor ESR below 10mΩ.
• What is the minimum output voltage that can be set using the FB pin?
  The minimum output voltage that can be set using the FB pin is 0.8V, but it's recommended to keep it above 1V for optimal performance and accuracy.
• How do I calculate the output voltage using the FB pin and the resistors R1 and R2?
  The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R2/R1). Make sure to choose R1 and R2 values that result in a stable and accurate output voltage.
• What is the maximum output current that the TPS54973PWPR can deliver?
  The maximum output current that the TPS54973PWPR can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
