The maximum input voltage that can be applied to the VIN pin is 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, ensure that the output capacitor is placed close to the device and connected to a low-impedance ground plane.
The maximum output current that the MP28115DQ-LF-Z can deliver is 1.5A. However, the output current should be derated based on the input voltage, output voltage, and ambient temperature.
The output voltage can be configured by connecting a resistor divider network between the VOUT pin and the GND pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2.
The EN (Enable) pin is used to enable or disable the device. When the EN pin is pulled high (above 1.4V), the device is enabled, and when it's pulled low (below 0.4V), the device is disabled. This pin can be used to implement power sequencing or to turn off the device when not in use.
