LT8390EFE#PBF Frequently Asked Questions (FAQs)

  • The LT8390 can handle input voltages up to 60V, but it's recommended to keep it below 50V for optimal performance and reliability.
  • To optimize the layout, keep the input and output capacitors close to the IC, use a solid ground plane, and minimize the length of the high-current paths. Also, ensure that the thermal pad is connected to a solid ground plane to improve heat dissipation.
  • A low-ESR ceramic capacitor (X5R or X7R dielectric) with a voltage rating of at least 2x the maximum input voltage is recommended. A 10uF to 22uF capacitor is a good starting point.
  • Choose an inductor with a saturation current rating above the peak current, a low DCR (less than 100mΩ), and a high SRF (above 10MHz). A 10uH to 22uH inductor is a good starting point.
  • The LT8390 can deliver up to 2A of output current, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
