LM2575D2T-3.3R4G Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure a stable output voltage, make sure to use the recommended output capacitor (10uF to 22uF) and keep the input voltage within the recommended range. Also, ensure good PCB layout and decoupling to minimize noise and ripple.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • The output voltage ripple and noise can be calculated using the formula: ΔVout = (ΔIout / Cout) * (Rout / (Rout + Rfb)), where ΔIout is the output current ripple, Cout is the output capacitor, Rout is the output resistance, and Rfb is the feedback resistance.
  • The thermal shutdown temperature is typically around 150°C to 160°C, but it's recommended to keep the junction temperature below 125°C for reliable operation.
