LTC3895EFE#PBF 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 switching node (SW pin) away from sensitive analog nodes, use a solid ground plane, and keep the high-current paths short and wide. Additionally, use a common-mode choke and a shielded inductor to reduce radiated emissions.
  • The recommended operating frequency range for the LTC3895EFE#PBF is between 100kHz to 500kHz. Operating outside of this range may affect the converter's efficiency and stability.
  • To select the right inductor, consider the maximum current rating, inductance value, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and an inductance value between 1uH to 10uH.
  • The SYNC pin is used to synchronize the switching frequency of multiple LTC3895EFE#PBF devices. To use it, connect the SYNC pins of multiple devices together, and ensure that the frequency of the SYNC signal is within the recommended range of 100kHz to 500kHz.
