LM3485MM Frequently Asked Questions (FAQs)

  • The LM3485MM 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 the recommended output capacitor value and type, and keep the input capacitor value below 10uF. Also, ensure the PCB layout is well-designed and follows good practices.
  • The minimum input voltage required for the LM3485MM to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The LM3485MM is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • The output voltage of the LM3485MM can be calculated using the formula: Vout = 1.24 * (1 + R2/R1), where R1 and R2 are the feedback resistors.
