Working Principle

The MP9148GJ-P is a DC/DC switching regulator. This type of regulator uses the principle of inductive energy storage and switches in order to regulate the output voltage. It is based on a voltage feedback loop, in which the output voltage is constantly monitored. If the output voltage drops below the target voltage, the controller circuits turn on the switching transistor, or switch, which causes the output voltage to increase. When the target voltage is reached, the switch is turned off again and the output voltage is stabilized. The repetition of this cycle causes the output voltage to remain stable.

The power from the input is delivered to the output through an inductor. When the switch is on, energy is stored in the inductor and when it is off, the energy is released to output. The addition of a diode provides a path for the current when the switch is off, resulting in a continuous flow of current even when the switch is off. The current limit is used to limit the current that flows through the switch and ensure stability of the system.
