LTC3780EUH#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3780EUH is 32V, but it's recommended to keep it below 28V for reliable operation.
  • To ensure the stability of the output voltage, 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.
  • The maximum output current that the LTC3780EUH can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation.
  • To configure the LTC3780EUH for a specific output voltage, use the feedback resistors R1 and R2 to set the output voltage. The ratio of R1 to R2 determines the output voltage. Use the formula: Vout = 0.8V * (1 + R2/R1) to calculate the output voltage.
  • The SYNC pin on the LTC3780EUH is used to synchronize the switching frequency of multiple LTC3780EUH devices. It allows multiple devices to operate in phase, reducing electromagnetic interference (EMI) and improving overall system performance.
