LT8315IFE#TRPBF Frequently Asked Questions (FAQs)

  • The LT8315 can handle input voltages up to 80V, but it's recommended to limit the input voltage to 60V for optimal performance and reliability.
  • To minimize EMI and noise, it's recommended to follow a star-grounding scheme, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW pin) away from sensitive nodes.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. X5R or X7R dielectric types are suitable for most applications.
  • The inductor value depends on the output voltage, output current, and switching frequency. A shielded inductor with a value between 1uH to 10uH is recommended. The inductor type should be chosen based on the desired trade-off between size, cost, and performance.
  • The LT8315 can deliver up to 2A of output current, but the actual output current capability depends on the input voltage, output voltage, and thermal conditions.
