LM2576WU-TR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2576WU-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 22uF, 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 LM2576WU-TR to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2576WU-TR 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.
  • To reduce the noise and ripple on the output voltage, use a low-ESR output capacitor, and add a noise-reducing capacitor (e.g. 10nF) between the output and ground. Also, use a shielded inductor and keep the layout compact to minimize radiated noise.
