LTC3896EFE#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 or ferrite bead on the input lines to filter out high-frequency noise.
  • The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic or polymer capacitor with a voltage rating of at least 2x the output voltage. X5R or X7R dielectric types are suitable for most applications.
  • The switching frequency of the LTC3896EFE#PBF can be adjusted by connecting a resistor (RT) between the RT pin and the GND pin. The switching frequency (fSW) is inversely proportional to RT, and the recommended range is 100kΩ to 500kΩ for a switching frequency range of 200kHz to 500kHz.
  • The maximum output current that the LTC3896EFE#PBF can deliver is 3A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
