LTC3858EUH#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V 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 ceramic capacitor for the output filter capacitor.
-
The SS pin is the soft-start pin, which allows the output voltage to ramp up slowly during startup. To use it, connect a capacitor from the SS pin to GND, and the soft-start time will be determined by the capacitor value and the internal current source.
-
The switching frequency can be adjusted by connecting a resistor from the RT pin to GND. The frequency will be determined by the resistor value, with lower values resulting in higher frequencies.
-
The maximum output current that the LTC3858EUH can deliver is 8A, but this can be limited by the thermal performance of the package and the PCB design.
