TPS5405DR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS5405DR is 60V, but it's recommended to keep it below 50V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a low-ESR capacitor for the output.
  • The maximum output current that the TPS5405DR can deliver is 5A, but it's recommended to keep it below 4A for reliable operation and to prevent overheating.
  • The output voltage of the TPS5405DR can be adjusted by using a resistor divider network between the output and the FB pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage of 0.8V.
  • The EN (enable) pin is used to turn the device on or off. When the EN pin is pulled low, the device is in shutdown mode and consumes very low current. When the EN pin is pulled high, the device is enabled and operates normally.
