LM2597HVMX-3.3/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 38V to ensure reliable operation and to prevent damage to the internal components.
  • The LM2597HVMX-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 may need to add thermal management or derate the output current at high temperatures.
  • To ensure stability, make sure to use the recommended output capacitor (22uF or higher) and input capacitor (10uF or higher) with low ESR. Also, keep the output voltage sense lines short and away from noise sources.
  • The LM2597HVMX-3.3/NOPB has a switching frequency of around 150kHz, which can generate noise. To minimize noise, use a shielded inductor, keep the layout compact, and add noise filters or shielding to the output lines if necessary.
  • The minimum input voltage is around 7V, but it's recommended to keep it above 8V to ensure reliable operation and to prevent dropout.
