TPS54873PWPR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54873PWPR is 6.5V. Exceeding this voltage may damage the device.
  • To ensure stability, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 4.7uF with an ESR of 0.1 ohm or less.
  • The TPS54873PWPR can deliver up to 3A of output current. However, the maximum output current may be limited by the input voltage, output voltage, and thermal considerations.
  • The output voltage of the TPS54873PWPR can be adjusted by using a resistor divider network between the output and the FB pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2.
  • The EN (enable) pin is used to turn the device on or off. When the EN pin is pulled low, the device is in shutdown mode and consumes minimal power. When the EN pin is pulled high, the device is enabled and operates normally.
