LM2596S-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 recommended output capacitor (10uF to 22uF) and input capacitor (10uF to 100uF) values, and keep the feedback resistors (R1 and R2) within the recommended range (1kΩ to 10kΩ).

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

  • The LM2596S-5.0/NOPB is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation. Use a heat sink if necessary.

  • The output voltage is determined by the feedback resistors (R1 and R2) and the internal reference voltage (1.23V). Use the formula: Vout = 1.23V x (1 + R2/R1).
