TPS74401KTWT Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
  • Choose an output capacitor with a value between 10uF to 22uF, and an ESR (Equivalent Series Resistance) of less than 1 ohm. X5R or X7R ceramic capacitors are recommended.
  • A minimum input capacitance of 1uF is recommended to ensure stability and prevent oscillations.
  • The TPS74401KTWT is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability and prevent thermal shutdown.
  • Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Make sure to keep the power dissipation below the maximum rating of 1.5W.
