LTC3119HFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3119HFE 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.
  • To minimize EMI and noise, keep the power stage components (L, C, and switches) close together, use a solid ground plane, and keep sensitive analog signals away from the power stage. Also, use a shielded inductor and consider adding a common-mode choke to reduce EMI.
  • To compensate the LTC3119HFE, use the recommended compensation components (R1, R2, C1, and C2) and follow the datasheet's compensation procedure. You can also use Analog Devices' compensation tool to simplify the process.
  • The maximum ambient temperature range for the LTC3119HFE is -40°C to 125°C, but the device's performance and reliability may degrade above 85°C.
