TPS5420QDRQ1 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS5420QDRQ1 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 TPS5420QDRQ1 to operate is 4.5V, but it's recommended to keep it above 5V for reliable operation.
  • Yes, the TPS5420QDRQ1 can operate in high-temperature environments, but the maximum junction temperature is 150°C. Make sure to derate the output current accordingly based on the ambient temperature.
  • The output voltage of the TPS5420QDRQ1 can be calculated using the formula: Vout = (R1 / R2) * (0.8V - Vfb), where R1 and R2 are the resistors in the feedback network, and Vfb is the feedback voltage.
