LM2597HVMX-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 22uF, and ensure the output capacitor has a low ESR (Equivalent Series Resistance) of less than 1 ohm.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • Choose an inductor with a value between 22uH and 47uH, and a current rating that exceeds the maximum output current. A higher inductor value can improve efficiency but may increase the physical size of the inductor.
  • The feedback pin is used to regulate the output voltage. Connect the feedback pin to the output voltage through a resistive divider network to set the desired output voltage.
