TPS79401DGNRG4 datasheet by Texas Instruments

TPS79401DGNRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79401DGNRG4?
  The maximum input voltage that can be applied to the TPS79401DGNRG4 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I ensure the stability of the output voltage in my design?
  To ensure the stability of the output voltage, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
• Can I use the TPS79401DGNRG4 in a high-temperature environment?
  The TPS79401DGNRG4 is rated for operation up to 125°C, but the output voltage and current may degrade at higher temperatures. Make sure to check the thermal derating curves in the datasheet to ensure the device can meet your requirements.
• How do I calculate the power dissipation of the TPS79401DGNRG4 in my design?
  The power dissipation of the TPS79401DGNRG4 can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
• Is the TPS79401DGNRG4 suitable for automotive applications?
  The TPS79401DGNRG4 is not AEC-Q100 qualified, which is a standard for automotive-grade components. However, it can still be used in automotive applications with proper design and testing to ensure reliability and performance.
