LM2671M-3.3 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2671M-3.3 is 15V, but it's recommended to keep it below 12V for reliable operation.
  • The LM2671M-3.3 is rated for operation up to 125°C, but the output voltage may decrease at high temperatures. It's recommended to derate the output current at high temperatures to ensure reliable operation.
  • The output voltage ripple of the LM2671M-3.3 can be calculated using the formula: ΔVout = (Iout x Rl) / (f x Cout), where Iout is the output current, Rl is the load resistance, f is the switching frequency, and Cout is the output capacitance.
  • The minimum input capacitance required for the LM2671M-3.3 is 10uF, but it's recommended to use a higher value (e.g. 22uF) to ensure stable operation and reduce input voltage ripple.
  • Yes, the LM2671M-3.3 can be used in a parallel configuration to increase the output current, but it's recommended to use a current-sharing scheme to ensure equal current distribution between the devices.
