LTC3779EFE#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • To minimize EMI, it's recommended to keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-frequency switching nodes (e.g., LX) away from sensitive analog nodes. Additionally, use a shielded inductor and orient it to minimize radiation.
  • The recommended operating frequency range for the LTC3779EFE#TRPBF is 100kHz to 1MHz. Operating outside this range may affect efficiency, stability, and EMI performance.
  • Select an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-10uH). Consider the inductor's physical size, core material, and operating frequency when making your selection.
  • The maximum output current that the LTC3779EFE#TRPBF can deliver is 2A. However, the actual output current may be limited by the input voltage, output voltage, and inductor selection.
