LTC3728IUH#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC3728IUH#PBF is 36V, but it's recommended to keep it below 30V 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, ensure that the output voltage is within the recommended range of 0.8V to 5.5V.
-
The maximum output current that the LTC3728IUH#PBF can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation and to prevent overheating.
-
To configure the LTC3728IUH#PBF for a specific output voltage, use a resistive divider network between the output and the FB pin to set the desired output voltage. The ratio of the resistors determines the output voltage.
-
The EN pin on the LTC3728IUH#PBF is an active-high enable pin that allows the user 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.
