TPS54040ADGQ Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54040ADGQ is 42V, but it's recommended to keep it below 40V 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 minimum input voltage required for the TPS54040ADGQ to operate is 4.5V, but it's recommended to keep it above 5V for reliable operation.
  • The TPS54040ADGQ is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Make sure to follow the thermal design guidelines to ensure reliable operation.
  • The output voltage of the TPS54040ADGQ can be calculated using the formula: Vout = (VFB / R2) * R1, where VFB is the feedback voltage (0.8V), R1 is the resistor connected between the output and the feedback pin, and R2 is the resistor connected between the feedback pin and ground.
