Buck converter is a type of DC-DC (Direct Current to Direct Current) power converter that is designed to step down or reduce the voltage from a higher value to a lower value while maintaining the power. In other words, it efficiently converts a higher input voltage to a lower output voltage.
Input Voltage: The buck converter takes in a higher voltage (DC).
Switching: The converter uses a switch (typically a transistor) to rapidly turn the input voltage on and off.
Inductor and Capacitor: An inductor and capacitor are used to smooth out the voltage fluctuations and store energy, ensuring the output is a steady DC voltage.
Output Voltage: The final output is a lower DC voltage, which is regulated based on the converter's design and control circuitry.
Module nature: non-isolated step-down module (BUCK) synchronous rectification
