TPS5450DDAG4 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS5450DDAG4 is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • 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.
  • The minimum input capacitance required is 4.7uF, but it's recommended to use a 10uF or larger capacitor to ensure stability and optimal performance.
  • The TPS5450DDAG4 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliability and prevent overheating.
  • The output voltage can be adjusted by changing the resistor divider ratio between the FB and VOUT pins. Use the formula in the datasheet to calculate the required resistor values.
