LM2596S-3.3 Frequently Asked Questions (FAQ)

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

  • No, the LM2596S-3.3 is a step-down (buck) converter and cannot be used as a boost converter.

  • The output voltage tolerance is typically ±2% of the nominal output voltage (3.3V). You can calculate it as ±(2% of 3.3V) = ±0.066V.

  • The minimum input voltage is 4V, but it's recommended to keep it above 5V for reliable operation.

  • The LM2596S-3.3 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation.
