The maximum input voltage that can be applied to the LM2575T-15G is 40V, but it's recommended to keep it below 35V for reliable operation.
To ensure a stable and regulated output voltage, make sure to use the recommended output capacitor (Cout) value of 10uF to 22uF, and keep the input capacitor (Cin) value between 1uF to 10uF. Also, ensure the PCB layout is well-designed to minimize noise and EMI.
The minimum input voltage required for the LM2575T-15G to operate is 7V, but it's recommended to keep it above 8V for reliable startup and operation.
The LM2575T-15G is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
To protect the LM2575T-15G from input voltage surges and spikes, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input, and ensure the input capacitor (Cin) is rated for the maximum input voltage.
