MP2208DL-LF-P Working Principle

The MP2208DL-LF-P is a current-mode switched mode power supply (SMPS) controller, meaning that it regulates output power by modulating the current through a predefined feedback loop. This is done by sensing the current through a sense resistor, and comparing it to the reference current provided by a voltage reference. If the sensed current exceeds the reference current, the controller will take necessary actions to reduce the current. Conversely, if the sensed current is less than the reference current, the controller will take necessary actions to increase the current.

The MP2208DL-LF-P also utilizes an oscillator for the switching operations and controls the on/off timing of the MOSFET switches via special logic circuitry. The on/off switching of the MOSFET switches modulates the output power of the power supply, while also controlling over-current/over-voltage/under-voltage protection and providing adjustable switching frequency. This allows for high efficiency and reliable power conversion.

Finally, the SMPS controller has a built-in over temperature protection, allowing it to shut down in the case of an over temperature situation. This provides an additional level of safety and protection to the power supply.
