A switching power supply board is a circuit board that converts the input voltage to the desired output voltage. It converts the input voltage into a high-frequency pulse signal through the switching operation of a switching component (such as a transistor or MOSFET), and then through filtering, voltage change and voltage regulation, outputs the required stable voltage to the target device. The switching power supply board has the following characteristics:

1. Rate: The switching power supply uses high-frequency pulse signals for voltage conversion, which can achieve a high conversion efficiency, generally more than 80%, which is higher than the traditional linear power supply efficiency.

2. Small size: The switching power supply uses high frequency operation, and smaller inductors and transformers can be used, thereby reducing the size of the entire power supply.

3. Wide input voltage range: Switching power supply can adapt to a wide input voltage range, usually can still provide a stable output voltage in the case of large input voltage fluctuations.

4. Stable output: The switching power supply board adjusts the output voltage through the feedback control circuit, which can provide a more stable output voltage, suitable for equipment with high voltage stability requirements.

5. A variety of protection functions: the switching power supply board usually has overload protection, overvoltage protection, overcurrent protection and other protection functions, which can protect the equipment from abnormal power supply damage. Switching power supply board is widely used in various electronic equipment, such as computers, televisions, mobile phone chargers, LED lighting fixtures and so on.
