TPS79401DGNT datasheet by Texas Instruments

TPS79401DGNT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS79401DGNT can handle?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I choose the right output capacitor for the TPS79401DGNT?
  Choose a capacitor with a value between 10uF to 22uF, and a voltage rating of at least 2x the output voltage. X5R or X7R ceramic capacitors are recommended.
• What is the minimum input capacitance required for the TPS79401DGNT?
  A minimum of 1uF input capacitance is recommended to ensure stability and prevent oscillations.
• Can I use the TPS79401DGNT in a high-temperature environment?
  The TPS79401DGNT is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
• How do I calculate the power dissipation of the TPS79401DGNT?
  Power dissipation (PD) = (Vin - Vout) x Iout. Ensure the PD is within the specified limit (1.5W) to prevent overheating.
