TPS5450DDAR Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the TPS5450DDAR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.

  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range and the output current is within the specified limits.

  • The maximum output current that the TPS5450DDAR can deliver is 5A, but it's recommended to keep it below 4A for optimal performance and reliability.

  • The output voltage of the TPS5450DDAR can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.

  • The EN (enable) pin on the TPS5450DDAR is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
