Power adapter application

It is widely used in consumer electronics, and the output power is mostly within 100 watts, and the market demand is growing rapidly. Applications such as electric bicycle battery chargers, small size LCD TVs, laptops, printers, DVD players and set-top boxes are available. Most of the early power adapters used linear transformers. As consumer electronics products have high efficiency, wide input voltage range, and increased copper, iron, and labor costs, the original linear transformers in these power adapters are gradually increasing. Replaced by switching power supply.
