LM2574HVM-3.3/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 40V, but it's recommended to keep it below 30V for reliable operation.

  • Make sure to use the correct output capacitor value (at least 10uF) and ensure the feedback pin is connected to the output capacitor's positive terminal.

  • A minimum of 10uF input capacitance is recommended to ensure stable operation, but a larger value (e.g., 22uF) is recommended for high-input-voltage applications.

  • The device is rated for operation up to 125°C, but thermal derating may be necessary for high-temperature applications. Ensure proper heat sinking and thermal management.

  • The output current capability is dependent on the input voltage and output voltage. Use the datasheet's efficiency graphs to estimate the maximum output current for your specific application.
