Working Principle

As mentioned above, the IR3800MTR1PBF consists of two power MOSFETs, one synchronous buck controller and some peripheral components. The MOSFETs will switch the voltage on to the output load in order to supply power with specified voltage and current. The duty cycle of the switch is controlled by the synchronous buck controller, which is connected to an external reference voltage. The duty cycle can be adjusted by varying the voltage of the reference voltage to allow the output voltage and current to be precisely regulated.In addition, the device also provides some advanced features such as the constant current mode and the fast transient response, which helps reduce the output voltage ripple and overload caused by the sudden current rise. This helps ensure the stable and reliable operation of the device even in the case of sudden current changes.

Conclusion
