LM2576-5.0WU Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2576-5.0WU is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure the output voltage is regulated to 5V, make sure to use the correct output capacitor value (at least 10uF) and ensure the input voltage is within the recommended range. Also, check that the feedback pin is properly connected to the output voltage through a resistive divider.
  • The minimum input voltage required for the LM2576-5.0WU to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2576-5.0WU 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.
  • The output current capability of the LM2576-5.0WU can be calculated using the formula: Iout = (Vin - Vout) / Rsc, where Rsc is the current sense resistor value.
