TPS54910PWPG4 datasheet by Texas Instruments

TPS54910PWPG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54910PWPG4?
  The maximum input voltage that can be applied to the TPS54910PWPG4 is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the TPS54910PWPG4 is stable and doesn't oscillate?
  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.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR can cause instability and affect the regulator's performance.
• Can I use the TPS54910PWPG4 in a high-temperature environment?
  The TPS54910PWPG4 is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curves provided in the datasheet.
• How do I calculate the output voltage of the TPS54910PWPG4?
  The output voltage of the TPS54910PWPG4 can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. Make sure to choose the correct resistor values to achieve the desired output voltage.
