LM2576SX-5.0/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.

  • Make sure to use the correct output capacitor (at least 10uF) and adjust the feedback resistors (R1 and R2) according to the datasheet to achieve a stable 5V output.

  • The minimum input voltage is 7V, but it's recommended to keep it above 8V for reliable operation.

  • The LM2576SX-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.

  • Use a TVS diode or a voltage clamp circuit to protect the input from voltage surges and spikes.
