LTC3108IGN#PBF datasheet by Linear Technology

LTC3108IGN#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC3108 can handle?
  The maximum input voltage that the LTC3108 can handle is 38V, but it's recommended to keep it below 36V for reliable operation.
• How do I optimize the inductor selection for the LTC3108?
  To optimize the 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 rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100mΩ.
• What is the purpose of the SYNC pin on the LTC3108?
  The SYNC pin is used to synchronize the switching frequency of multiple LTC3108 devices in a system, ensuring that they operate in phase and reducing electromagnetic interference (EMI).
• How do I configure the LTC3108 for a specific output voltage?
  To configure the LTC3108 for a specific output voltage, use the FB pin and a resistive divider network to set the output voltage. The FB pin is connected to the output voltage through a resistive divider, and the ratio of the resistors determines the output voltage.
• What is the minimum input capacitance required for the LTC3108?
  The minimum input capacitance required for the LTC3108 is 10μF, but it's recommended to use a higher value (e.g., 22μF) to ensure stable operation and minimize input voltage ripple.
