The MP2149GJ-Z can handle a maximum input voltage of 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
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, keep the output voltage within the recommended range of 0.8V to 15V.
The MP2149GJ-Z can provide a maximum output current of 2A, but it's recommended to keep it below 1.5A for optimal performance and reliability.
The output voltage can be adjusted by using a resistive divider network between the FB pin and the output voltage. The ratio of the resistors determines the output voltage, and the datasheet provides a formula to calculate the required resistor values.
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. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
