LM2576T-12/LF03 Frequently Asked Questions (FAQ)

  • 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 the PCB layout is well-designed to minimize noise and EMI.

  • The minimum input voltage required is 7V, but it's recommended to keep it above 8V for reliable operation.

  • The LM2576T-12/LF03 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 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, and Cout is the output capacitor value.
