LTC3115IFE-2#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin 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 power traces short and wide, and use a solid ground plane. Place the input capacitors close to the VIN pin, and the output capacitors close to the VOUT pin. Keep the switching node (SW pin) away from sensitive nodes.
  • To configure the LTC3115 for a specific output voltage, use the FB pin and a resistive divider to set the output voltage. The FB pin voltage is 0.8V, so choose resistors that will produce this voltage at the desired output voltage.
  • The maximum ambient temperature for the LTC3115 is 125°C, but it's recommended to keep it below 85°C for reliable operation.
