LTC3784IUFD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3784IUFD is 36V, but it's recommended to keep it below 32V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the input capacitor (CIN) and output capacitor (COUT).
  • The maximum output current that the LTC3784IUFD can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation.
  • To configure the LTC3784IUFD for a specific output voltage, use the feedback resistors (RFBT and RFB) to set the output voltage. The ratio of RFBT to RFB determines the output voltage. Use the formula: VOUT = 0.8V x (1 + RFBT/RFB) to calculate the output voltage.
  • The EN/UVLO pin is used to enable or disable the regulator. When the pin is pulled high, the regulator is enabled. When the pin is pulled low, the regulator is disabled. The pin also has an undervoltage lockout (UVLO) function, which disables the regulator if the input voltage falls below a certain threshold (typically around 2.5V).
