TPS54315PWPR datasheet by Texas Instruments

TPS54315PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54315PWPR?
  The maximum input voltage that can be applied to the TPS54315PWPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.
• What is the minimum input capacitance required for the TPS54315PWPR?
  The minimum input capacitance required for the TPS54315PWPR is 10uF, but it's recommended to use a higher value (22uF or more) for better performance and stability.
• Can I use the TPS54315PWPR in a high-temperature environment?
  The TPS54315PWPR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability and prevent overheating.
• How do I calculate the output voltage of the TPS54315PWPR?
  The output voltage of the TPS54315PWPR can be calculated using the formula: Vout = (R1 / R2) * 0.8V, where R1 and R2 are the resistors connected to the FB pin.
