TPS5450DDAG4 datasheet by Texas Instruments

TPS5450DDAG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS5450DDAG4?
  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.
• How do I ensure the TPS5450DDAG4 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 input capacitance required for the TPS5450DDAG4?
  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.
• Can I use the TPS5450DDAG4 in a high-temperature environment?
  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.
• How do I adjust the output voltage of the TPS5450DDAG4?
  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.
