LM2575T-12/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • Use a high-quality output capacitor with low ESR (Equivalent Series Resistance) and ensure the feedback resistors are of high precision (1% or better) to minimize output voltage error.
  • The minimum input voltage is 7V, but it's recommended to keep it above 8V for reliable startup and operation.
  • Yes, but the device is rated for operation up to 125°C. Ensure proper thermal design and heat sinking to prevent overheating.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the input from voltage surges or spikes.
