It can either use a voltage detection circuit or a current detection circuit. According to the requirement of the output voltage, the current output from this loop will be controlled to ensure that the output voltage remains stable.

Buck converters. Buck converters convert high input voltages to low output voltages. It consists of a power switch, an inductor, a capacitor, and a control circuit. The power switch is used to receive the input voltage, and then block the input voltage, and then switch to the output voltage. The inductor and capacitor work together to form a low-pass filter, and the control circuit adjusts the on and off time of the power switch to maintain a stable output voltage.
