Working Principles
The MAX1874ETE+ operates on the principle of step-down conversion, also known as buck conversion. It utilizes a high-frequency switching transistor to rapidly switch the input voltage across an inductor. This creates a varying magnetic field that stores energy during the "on" state and releases it during the "off" state. The energy is then transferred to the output capacitor, resulting in a regulated output voltage.
