LTC3113IFE#PBF datasheet by Linear Technology

LTC3113IFE#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the VIN pin?
  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.
• How do I optimize the inductor selection for the LTC3113?
  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.
• What is the purpose of the RUN pin, and how do I use it?
  The RUN pin is an active-high enable input that allows the user to turn the converter on and off. To use it, connect the RUN pin to a logic-level signal (e.g., from a microcontroller) to enable or disable the converter.
• How do I configure the LTC3113 for a specific output voltage?
  To configure the LTC3113 for a specific output voltage, use the FB pin and a resistive divider 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 maximum output current that the LTC3113 can deliver?
  The maximum output current that the LTC3113 can deliver is 3A, but it's limited by the input voltage, inductor selection, and thermal considerations.
