LM2597HVM-ADJ/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 60V, but it's recommended to keep it below 50V for reliable operation.
  • Use a high-quality output capacitor with low ESR, and ensure the feedback resistors are of high precision (1% or better). Also, keep the output capacitor close to the IC to minimize noise.
  • The minimum input voltage is 4.5V, but it's recommended to keep it above 6V for reliable operation.
  • Yes, but the device is rated for operation up to 125°C. Above this temperature, the device's performance and reliability may degrade. Ensure proper thermal management and derate the output current accordingly.
  • The output voltage is calculated using the formula: Vout = 1.23 * (1 + R2/R1), where R1 and R2 are the feedback resistors. Ensure the resistors are of high precision to achieve accurate output voltage.
