TPS54225PWP datasheet by Texas Instruments

TPS54225PWP Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54225PWP?
  The maximum input voltage that can be applied to the TPS54225PWP is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value, as recommended in the datasheet.
• What is the minimum input voltage required for the TPS54225PWP to operate?
  The minimum input voltage required for the TPS54225PWP to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup.
• Can I use the TPS54225PWP in a high-temperature environment?
  Yes, the TPS54225PWP can operate in high-temperature environments, but the maximum junction temperature should not exceed 150°C. Make sure to follow the thermal design guidelines in the datasheet to ensure reliable operation.
• How do I calculate the output voltage of the TPS54225PWP?
  The output voltage of the TPS54225PWP can be calculated using the formula: Vout = (R1 / R2) * (1 + R2 / R3) * Vref, where R1, R2, and R3 are the resistors in the feedback network, and Vref is the internal reference voltage (1.21V).
