Working Principle

The VI-21Z-IY-F4 DC-DC converter works according to the buck, boost, or buck-boost principles. In the buck and buck-boost modes, the DC voltage is regulated by transforming the input voltage into a lower, more regulated voltage. The conversion is achieved through the use of a step-down transformer or inductor. In a buck-boost converter, the input voltage is transformed into both higher and lower voltages, depending on the direction the polarity of the transformer is connected.

The output of the converter is regulated using a variable current source or a voltage regulator. This current source works by detecting the voltage across the output capacitor and adjusting the output voltage accordingly. In a buck configuration, the output voltage is reduced, while in a boost configuration, the output voltage is increased. As the core of the system, the voltage regulator is responsible for ensuring the output voltage maintained within its specified limits.
