LTC3108EGN-1#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 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 above the peak current of the converter and a DC resistance that minimizes losses.
• 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, simply tie the RUN pin to VIN or a logic high signal to enable the converter, or tie it to GND or a logic low signal to disable it.
• How do I adjust the output voltage of the LTC3108?
  The output voltage of the LTC3108 can be adjusted by changing the resistor divider ratio between the VOUT pin and the GND pin. The output voltage is determined by the formula: VOUT = 0.6V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider.
• What is the maximum ambient temperature range for the LTC3108?
  The maximum ambient temperature range for the LTC3108 is -40°C to 125°C, but the device can operate up to 150°C with derating.
