LM2597HVN-ADJ/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 37V to ensure reliable operation and to prevent damage to the internal components.
  • The output voltage can be set by connecting a resistor divider network between the output pin and the adjust pin. The formula to calculate the output voltage is Vout = 1.23V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
  • The minimum input voltage required is 4V, but it's recommended to keep it above 5V to ensure reliable operation and to prevent dropout.
  • The LM2597HVN-ADJ/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation.
  • To ensure stability, it's recommended to use a minimum output capacitance of 22uF, and to keep the output voltage ripple below 1% of the output voltage. Additionally, the input voltage should be well-regulated and free of noise.
