Working Principle of V375A24H600BS3

The working principle of the V375A24H600BS3 is based on an isolated flyback topology. In general, the input current from the rectified AC source is processed by a full bridge rectifier plus a current limiting device, such as a resistor. The output voltage is then regulated by a feedback line that monitors the output voltage and adjusts the duty cycle of an internal switch to keep the output voltage more or less constant. The main benefit of the flyback topology is the primary switched current is limited and does not increase when loading increases. This in turn eliminates the need for large filtering capacitors, reducing size and cost. Moreover, it offers low EMI.
