TPS54429PWPR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54429PWPR is 18V. Exceeding this voltage may damage the device.
  • To ensure stability, it is recommended to use a minimum output capacitance of 10uF, and to place the output capacitor close to the device. Additionally, the input capacitor should be at least 1uF and placed close to the input pin.
  • The maximum output current that the TPS54429PWPR can deliver is 4A. However, the output current should be derated based on the ambient temperature and the input voltage.
  • The output voltage of the TPS54429PWPR can be adjusted by using a resistive divider network between the output and the FB pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1/R2 + 1), where R1 and R2 are the resistors in the divider network.
  • The EN (enable) pin is used to turn the device on or off. When the EN pin is pulled high, the device is enabled and operates normally. When the EN pin is pulled low, the device is disabled and the output voltage is turned off.
