LM2574N-12/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2574N-12 is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure a stable and regulated output voltage, make sure to use the recommended output capacitor value (typically 10uF to 22uF) and keep the input voltage within the recommended range. Also, ensure that the input and output capacitors are of high quality and have low ESR (Equivalent Series Resistance).
  • The minimum input voltage required for the LM2574N-12 to operate is around 7V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2574N-12 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • The output voltage ripple of the LM2574N-12 can be calculated using the formula: ΔVout = (Iout x Rload) / (f x Cout), where ΔVout is the output voltage ripple, Iout is the output current, Rload is the load resistance, f is the switching frequency, and Cout is the output capacitance.
