LTC3445EUF#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the VIN pin is 5.5V, as specified in the Absolute Maximum Ratings section of the datasheet. Exceeding this voltage can damage the device.
-
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1Ω or less, as specified in the datasheet. Additionally, the output voltage should be decoupled with a 1uF ceramic capacitor to reduce noise and oscillations.
-
The maximum output current that can be drawn from the device is 500mA, as specified in the datasheet. Exceeding this current can cause the device to overheat and reduce its reliability.
-
The output voltage can be configured by connecting a resistive divider network between the VOUT pin and the GND pin, with the FB pin connected to the center tap of the divider. The output voltage is determined by the ratio of the resistors in the divider network.
-
The EN pin is an active-high enable input that allows the device to be turned on or off. When the EN pin is high, the device is enabled and operates normally. When the EN pin is low, the device is disabled and the output voltage is turned off.
