The maximum input voltage that can be applied to the LTC3113EFE is 40V, but it's recommended to keep it below 36V for reliable operation.
To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core loss. A good starting point is to choose an inductor with a saturation current at least 1.5 times the maximum output current and a DC resistance less than 100mΩ.
To minimize EMI and noise, keep the power traces short and wide, use a solid ground plane, and place the input and output capacitors close to the IC. Also, avoid routing sensitive signals near the inductor and use a shielded inductor if possible.
To configure the LTC3113EFE for a specific output voltage, use the FB pin and a resistive divider to set the output voltage. The resistive divider should be connected between the output voltage and ground, with the FB pin connected to the center tap of the divider.
The maximum output current that the LTC3113EFE can deliver is 3A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
