Working Principle

0936010664 is a step-down switching power supply. It adopts a two-stage design approach, namely, apower factor correction (PFC) stage and a DC/DC step-down conversion DC/DC stage. The power factor correction stage is a boost topology. The primary side uses an AC/DC rectification bridge circuit to rectify the input from the AC power grid. Next, the rectified waveforms are filtered by the electrolytic capacitor to obtain a DC voltage, then it is passed through the power factor correction chip to generate the required input voltage to the boost circuit. The voltage is boosted and outputted. The boost circuit is composed of a power switch, a driving circuit, a frequency compensation circuit and an output filtering circuit. When the switch is working, the power switch is turned on first and the current begins to increase.

After passing through the inductor, the current is outputted to the output capacitor, and the inductor stores energy when the switch is turned on. When the switch is turned off, the stored energy is released to the output in the form of a continuous current and a voltage is formed on the output end. Then, the DC/DC stage is a step-down conversion circuit. Through the control of the operating frequency of the power switch, the current output from the PFC stage is converted into the required voltage and then output it to the load. The conversion rate of the two-stage design is high and the generated power can reach 86%.

Conclusion

The 0936010664 switching power supply module is a digital micro power switching power supply module with strong performance and excellent reliability. This module is mainly used in the communication, digital products, small electronic appliances and automation control fields. It has a two-stage design, namely PFC and DC/DC step-down conversion, which can make full use of the input electric power to make the power conversion rate to reach 86%.
