TPS54550PWPR datasheet by Texas Instruments

TPS54550PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54550PWPR?
  The maximum input voltage that can be applied to the TPS54550PWPR is 60V, but it's recommended to keep it below 50V for optimal performance and reliability.
• How do I ensure the TPS54550PWPR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and use a minimum output capacitance of 10uF with an ESR of 10mΩ or less.
• What is the minimum input capacitance required for the TPS54550PWPR?
  The minimum input capacitance required is 1uF, but it's recommended to use a higher value (e.g., 4.7uF) to ensure stability and reduce input voltage ripple.
• Can I use the TPS54550PWPR in a high-temperature environment?
  Yes, the TPS54550PWPR is rated for operation up to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
• How do I calculate the output voltage of the TPS54550PWPR?
  The output voltage (VOUT) can be calculated using the formula: VOUT = (VFB x (R1 + R2) / R2), where VFB is the feedback voltage (0.8V typical), R1 is the upper resistor, and R2 is the lower resistor in the voltage divider.
