LM2574HVN-15/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 a stable output voltage, make sure to use the recommended output capacitor (10uF to 22uF) and keep the input voltage within the recommended range. Also, ensure the PCB layout is well-designed to minimize noise and electromagnetic interference.
  • The minimum input voltage required is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2574HVN-15/NOPB is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation. Make sure to provide adequate heat sinking and thermal management.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout x Rl) / (f x Cout), where Iout is the output current, Rl is the load resistance, f is the switching frequency, and Cout is the output capacitance.
