LM2576S-5.0 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2576S-5.0 is 40V, but it's recommended to keep it below 35V for reliable operation.

  • To ensure the output voltage is exactly 5.0V, use a 1% tolerance resistor for R1 and R2, and make sure the output capacitor is a low-ESR type. Also, ensure the input voltage is within the recommended range.

  • The minimum input voltage required for the LM2576S-5.0 to operate is 7V, but it's recommended to keep it above 8V for reliable operation.

  • The LM2576S-5.0 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 transient voltage suppressor in parallel with the input capacitor to protect the LM2576S-5.0 from input voltage surges.
