As a common switching power supply topology, flyback charger and adapter are mainly used for low-power power supply needs. Its core parts are transformer and MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) switch tube.

When the switch tube is turned on, the input voltage acts on the primary of the transformer to store energy. When the switch tube is turned off, the stored energy acts on the load through the secondary coil of the transformer. Then it is converted into DC through the rectifier.

Advantages of flyback charger and adapter:

1. Simple and stable structure, no need for too many components, and the design is relatively intuitive.

2. Better isolation, input and output isolation through transformer to improve safety.

3. Higher efficiency, more suitable for low-power cases.

4. Relatively small size, cost saving, increased portability.

5. The output range is relatively flexible, and the number of turns of the transformer is increased or decreased according to the output power.

Henryuan flyback power supply has been widely used in low-power power supply applications due to its simple design, good electrical isolation, competitive price, and complete safety certification (CB, CE, UKCA, GS, UL, cUL, FCC, EMC, LVD, SAA, KC, CCC and other safety certifications), and has good market feedback.
