LM2596S-5.0/NOPB datasheet by Texas Instruments

LM2596S-5.0/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2596S-5.0/NOPB?
  The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  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).
• What is the minimum input voltage required for the LM2596S-5.0/NOPB to operate?
  The minimum input voltage is 7V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM2596S-5.0/NOPB in a high-temperature environment?
  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.
• How do I calculate the output voltage of the LM2596S-5.0/NOPB?
  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).
