LM3481MMX/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3481MMX/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
  • The maximum output current that the LM3481MMX/NOPB can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • The output voltage of the LM3481MMX/NOPB 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 of the LM3481MMX/NOPB is 150°C. The device will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 130°C.
