LTC3109EGN#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LTC3109 can handle is 38V, but it's recommended to keep it below 36V for reliable operation.
  • 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 at least 1.5 times the peak current, and a DC resistance less than 100mΩ.
  • For optimal performance, keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise. Also, keep the inductor away from sensitive analog signals and use a shielded inductor if possible.
  • First, check the input voltage and current, and ensure that the input capacitor is properly sized. Then, verify that the inductor is not saturating and that the output voltage is within the expected range. Finally, check for any noise or oscillations on the output voltage.
  • The LTC3109 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure that the device is properly heatsinked and that the ambient temperature is within the recommended range.
