LTC3857EUH#TRPBF 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 capacitor for the input capacitor.
-
The maximum output current that the LTC3857EUH can deliver is 7A, but it's recommended to keep it below 5A for reliable operation.
-
The output voltage can be adjusted by using a resistive divider network between the VOUT pin and the GND pin. The output voltage is determined by the ratio of the resistors in the divider network.
-
The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
