TPS54425PWPR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54425PWPR is 25V. Exceeding this voltage may damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled from the input voltage using a capacitor with a value of at least 1uF.
  • The maximum output current that the TPS54425PWPR can deliver is 4A. Exceeding this current may cause the device to overheat or shut down.
  • The output voltage of the TPS54425PWPR can be adjusted by using a resistor divider network between the output voltage pin and the ground pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
  • The thermal shutdown temperature of the TPS54425PWPR is 150°C. If the device temperature exceeds this value, it will shut down to prevent damage.
