LTC3113 - IC 16 A SWITCHING REGULATOR, 2000 kHz SWITCHING FREQ-MAX, PDSO16, 5 X 4 MM, 0.75 MM HEIGHT, LEAD FREE, PLASTIC, MO-229WJGD-2, DFN-16, Switching Regulator or Controller
The maximum input voltage that can be applied to the LTC3113 is 40V, but it's recommended to keep it below 36V for reliable operation.
To optimize inductor selection, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current at least 1.5 times the peak current, and a DC resistance less than 100mΩ.
For optimal performance, keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise. Keep the high-current paths (e.g., from the inductor to the output capacitor) short and wide, and avoid routing sensitive signals near the inductor.
To configure the LTC3113 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 LTC3113 can deliver depends on the input voltage and the inductor selection. Typically, it can deliver up to 3A of output current, but this can be limited by the inductor's saturation current and the IC's thermal performance.
