LM2576HVSX-12/NOPB 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 value (10uF to 22uF) and keep the input voltage within the recommended range. Also, ensure the PCB layout is well-designed to minimize noise and EMI.
  • 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 can be calculated using the formula: ΔVout = (Iout x Rload) / (f x Cout), where Iout is the output current, Rload is the load resistance, f is the switching frequency (52kHz for the LM2576HVSX-12/NOPB), and Cout is the output capacitor value.
  • The feedback pin (FB) is used to regulate the output voltage. Connect a resistive divider from the output voltage to the FB pin to set the desired output voltage. The recommended resistive divider ratio is 1:1.2 for a 12V output.
