TPS54973PWP Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54973PWP 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 placement guidelines, use a sufficient output capacitor (at least 10uF), and add a small ceramic capacitor (around 10nF) between the VIN and GND pins to filter out noise.
  • The minimum ESR required for the output capacitor is 10mΩ, but it's recommended to use a capacitor with an ESR of 5mΩ or lower for optimal performance.
  • The TPS54973PWP is rated for operation up to 125°C, but it's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet to ensure reliability.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
