LT8390AEFE#TRPBF 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 minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and wide. Also, consider using a shielded inductor and orienting the IC to minimize radiation.
  • The recommended PCB footprint for the LT8390 is a 4-layer board with a solid ground plane, and a thermal pad connected to the exposed pad of the IC. The footprint should be designed to minimize thermal resistance and ensure good heat dissipation.
  • Select an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value based on the switching frequency and output voltage. A shielded inductor is recommended to minimize EMI.
  • The LT8390 can deliver up to 2A of output current, but the actual output current capability depends on the input voltage, output voltage, and thermal conditions.
