AC-DC controller is the core control chip of the switching power supply, responsible for efficiently and stably converting AC power (mains 110/220V AC) into DC power (such as 5V/12V/24V DC), and is the "power heart" of all plug-in electronic devices.

Function:
1. Wide voltage input: 85-265V AC, globally applicable.
2. High efficiency: mainstream products>85%, energy-saving and low heating.
3. Isolation safety: meet safety regulations and prevent electric shock.
4. Low standby power consumption: compliant with Energy Star (<75mW).
5. Simple periphery: high integration and few components.

Typical Applications:
1. Consumer electronics (most widely used)
    Mobile/tablet fast charging, laptop power adapter
    Home appliances: TV, refrigerator, washing machine internal power board
    Digital products: routers, optical modem, printers, monitor power supplies
2. Industry and Control
    PLC and industrial control power supply, sensor power supply
    Servo drive, motor control auxiliary power supply
    LED driver power supply (outdoor lighting, landscape lights)
3. Communication and servers
    Base station power supply, redundant power supply for servers
    Communication equipment, PoE power supply module
4. New energy and automobiles
    Internal AC-DC module of charging station
    Photovoltaic inverters, energy storage systems
    Car OBC (car charger), car electronic power supply
