LTC3111EDE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3111 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 rating above the peak current of the converter, and a DC resistance that minimizes losses.
  • For optimal performance, keep the power components (inductor, capacitors, and switches) close together, and use a solid ground plane to reduce noise and EMI. Keep the feedback network components (RFBT, CFBT) close to the FB pin, and use a separate analog ground plane for the feedback network.
  • To compensate the LTC3111, use a Type II compensation network (RFBT, CFBT, and CF) to achieve a stable loop gain. The datasheet provides a compensation calculator to help with the design.
  • The maximum output current capability of the LTC3111 is 2A, but it can be limited by the inductor selection, input voltage, and thermal considerations.
