LM2576-3.3WU-TR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2576-3.3WU-TR is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the output filter capacitor.
  • The minimum input voltage required for the LM2576-3.3WU-TR to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2576-3.3WU-TR is rated for operation up to 125°C, but it's recommended to derate the output current at high temperatures to prevent overheating.
  • The output voltage ripple of the LM2576-3.3WU-TR can be calculated using the formula: ΔVout = (Iout x Rload) / (fsw x Cout), where Iout is the output current, Rload is the load resistance, fsw is the switching frequency, and Cout is the output capacitance.
