LT8392EFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT8392EFE can handle is 60V, but it's recommended to operate it within the 4.5V to 40V range for optimal performance.
  • To minimize EMI, it's recommended to follow a star-ground configuration, 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) away from sensitive nodes.
  • The recommended inductor value is 1.5μH to 3.3μH, and it's recommended to use a shielded inductor with a low DCR (DC resistance) to minimize losses. A ferrite core inductor is a good option.
  • Select output capacitors with a low ESR (equivalent series resistance) and a high ripple current rating. Ceramic capacitors (X5R or X7R) or polymer capacitors are good options. The output capacitor value should be at least 10μF to ensure stability.
  • The thermal derating curve for the LT8392EFE is not explicitly stated in the datasheet, but it's recommended to derate the output current by 1.5% per degree Celsius above 25°C to ensure reliable operation.
