LTC3892IUH#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 reduce common-mode noise.
  • The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic or polymer capacitor to minimize output voltage ripple and ensure stability.
  • The switching frequency of the LTC3892IUH#PBF can be adjusted by connecting a resistor (RT) between the RT pin and the GND pin. The switching frequency can be calculated using the formula: fSW = 1 / (RT * 10^6).
  • The maximum output current that the LTC3892IUH#PBF can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
