NB671LBGQ-Z Frequently Asked Questions (FAQs)

  • The maximum input voltage is 26V, but it's recommended to keep it below 24V for optimal performance and to prevent overheating.
  • To ensure stability, use a minimum output capacitance of 1µF with an ESR (Equivalent Series Resistance) of 0.1Ω or less, and place the capacitor close to the output pin.
  • A minimum input capacitance of 1µF is recommended to ensure stability and prevent oscillations, but a larger capacitance (e.g., 4.7µF) can be used for improved noise rejection.
  • The NB671LBGQ-Z is rated for operation up to 125°C, but the junction temperature (TJ) should be kept below 150°C to ensure reliability and prevent thermal shutdown.
  • Calculate the power dissipation (PD) using the formula: PD = (VIN - VOUT) x IOUT. Then, use the thermal resistance (θJA) and maximum junction temperature (TJ) to determine the required heat sink size and thermal interface material.
