TPS56921PWPR datasheet by Texas Instruments

TPS56921PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS56921PWPR?
  The maximum input voltage that can be applied to the TPS56921PWPR 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 in my design?
  To ensure the stability of the output voltage, make sure to follow the recommended layout guidelines, use a sufficient output capacitor (at least 10uF), and keep the input voltage ripple below 100mV.
• What is the minimum input voltage required for the TPS56921PWPR to operate?
  The minimum input voltage required for the TPS56921PWPR to operate is 2.7V, but it's recommended to keep it above 3.5V for optimal performance.
• Can I use the TPS56921PWPR in a high-temperature environment?
  Yes, the TPS56921PWPR can operate in high-temperature environments up to 125°C, but the output current may need to be derated to ensure reliability.
• How do I calculate the output voltage of the TPS56921PWPR?
  The output voltage of the TPS56921PWPR can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
