LM2675N-3.3/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2675N-3.3/NOPB is 40V, but it's recommended to keep it below 38V to ensure reliable operation.
  • The LM2675N-3.3/NOPB has a maximum operating junction temperature of 150°C, but it's recommended to keep the temperature below 125°C for reliable operation. You can use thermal management techniques like heat sinks or thermal interfaces to reduce the temperature.
  • To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 22uF. You can also add a 10nF ceramic capacitor in parallel with the output capacitor to improve stability.
  • The minimum input capacitance required for the LM2675N-3.3/NOPB 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 LM2675N-3.3/NOPB is a switching regulator and can be used in a switching mode power supply. It has a built-in switching transistor and operates at a frequency of around 260kHz.
