LM3481MM Frequently Asked Questions (FAQs)

  • The LM3481MM can handle input voltages up to 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 keep the input and output capacitors close to the IC. Also, use a low-ESR capacitor for the output capacitor.
  • The LM3481MM can provide up to 3A of output current, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • The output voltage of the LM3481MM can be adjusted by using a resistive divider network between the output and the feedback pin. The ratio of the resistors determines the output voltage.
  • The LM3481MM has a thermal shutdown temperature of around 150°C. If the junction temperature exceeds this value, the IC will shut down to prevent damage.
