LM2574HVM-5.0 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2574HVM-5.0 is 60V, but it's recommended to keep it below 50V for reliable operation.
  • To ensure the output voltage is regulated to 5V, make sure to use the correct output voltage divider resistors (R1 and R2) and that the output capacitor (Cout) is of sufficient value (at least 10uF) and type (low ESR).
  • The minimum input capacitance required for stable operation is 10uF, but it's recommended to use a higher value (at least 22uF) to ensure stability over the entire operating range.
  • Yes, the LM2574HVM-5.0 is rated for operation up to 125°C, but the output current may need to be derated at higher temperatures to prevent overheating.
  • To protect the LM2574HVM-5.0 from input voltage surges, use a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input to limit the voltage to 60V or less.
