Working Principle

The V28A12C200BF3 DC-DC converter operates on the principle of switching power conversion. When an input voltage is applied to the converter, the internal switching device begins switching energy from the input to the output. As the switch transitions from one state to another, the internal power transformer is magnetically coupled to the switching device, and then the transformed energy is rectified and filtered to a usable output voltage. As the switching frequency increases, more energy can be transferred to the output, allowing for higher current and improved efficiency.
