LTC3649IFE#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC3649IFE is 28V, but it's recommended to operate within the specified input voltage range of 4.5V to 24V for optimal performance.
-
To ensure the stability of the output voltage, it's essential to follow the recommended layout guidelines, use a suitable output capacitor, and ensure that the input voltage is within the specified range. Additionally, the output voltage can be adjusted using the FB pin, and the output voltage stability can be improved by adding a capacitor in parallel with the output capacitor.
-
The EN (enable) pin is used to enable or disable the regulator. When the EN pin is pulled high (above 1.2V), the regulator is enabled, and when it's pulled low (below 0.4V), the regulator is disabled. This pin can be used to implement power sequencing or to turn the regulator on and off as needed.
-
The output voltage of the LTC3649IFE can be calculated using the following formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage can be adjusted by changing the values of R1 and R2.
-
The maximum output current that the LTC3649IFE can deliver is 1.5A. However, the output current should be derated based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
