LM2575HVT-3.3/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2575HVT-3.3/NOPB is 60V. However, it's recommended to keep the input voltage below 50V for reliable operation.
  • The LM2575HVT-3.3/NOPB is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • To ensure stability, make sure to use the recommended output capacitor value and type, and keep the input and output capacitors close to the IC. Also, ensure that the PCB layout is well-designed and follows good practices for switching regulators.
  • The LM2575HVT-3.3/NOPB has a minimum input voltage of 7V, so it's not suitable for low-input-voltage applications. For applications with input voltages below 7V, consider using a different regulator or a boost converter.
  • The output voltage ripple of the LM2575HVT-3.3/NOPB can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
