TPS54550PWPRG4 datasheet by Texas Instruments

TPS54550PWPRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54550PWPRG4?
  The maximum input voltage that can be applied to the TPS54550PWPRG4 is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure the TPS54550PWPRG4 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a 10nF-100nF ceramic capacitor between the VIN and GND pins to filter out noise.
• What is the minimum input voltage required for the TPS54550PWPRG4 to operate?
  The minimum input voltage required for the TPS54550PWPRG4 to operate is 4.5V, but it's recommended to keep it above 5V for reliable startup and operation.
• Can I use the TPS54550PWPRG4 in a high-temperature environment?
  The TPS54550PWPRG4 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the TPS54550PWPRG4?
  The output voltage of the TPS54550PWPRG4 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.
