PG02S4805A Working Principle

The working principle of the PG02S4805A can be explained with the help of the below schematic:

The PG02S4805A uses a step-down switching regulator circuit, which is composed of a power inductor, a power diode, and an internal switching regulator IC. When the input voltage is applied to the converter, the internal switching regulator IC will send a signal to the power inductor. The power inductor will then store the current, and the power diode will ensure the current flow in the correct direction. The internal IC will continuously regulate the voltage and current output level by controlling the switching speed of the power inductor. This ensures a steady output voltage and current, regardless of the fluctuating input voltage.
