LTC3851EUD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3851EUD is 28V, but it's recommended to keep it below 24V for reliable operation.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed close to the output pin to minimize parasitic inductance.
  • The SYNC pin is used to synchronize the switching frequency of multiple LTC3851EUD devices in a system, ensuring that they operate in phase and reducing electromagnetic interference (EMI).
  • The switching frequency of the LTC3851EUD can be adjusted by connecting a resistor (RT) between the RT pin and GND. The frequency can be calculated using the formula: fSW = 1.25 / (RT x 10^(-4)).
  • The maximum current that the LTC3851EUD can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
