LM3477MM/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage 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, use a 1uF ceramic capacitor at the input pin.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • The output voltage can be calculated using the formula: Vout = 1.24 * (1 + R2/R1), where R1 and R2 are the resistors connected to the feedback pin.
  • The thermal shutdown temperature is 150°C, and the device will automatically shut down if the junction temperature exceeds this value.
