The LNK562DG AC/DC power supply controller is a high-performance integrated circuit that provides an economical solution for a variety of off-line AC to DC power conversion applications. It provides a wide input voltage range of 85V to 265V and helps minimize the size of the power supply system components, simplify design and reduce cost. This integrated circuit includes a 700V MOSFET, an oscillator, current sensing, overvoltage and undervoltage protection, and a soft start.

The LNK562DG is an isolated, offline, high-voltage power supply controller IC. It provides very low no-load power consumption, high energy efficiency, and fast transient response. The device also has protections for overvoltage, undervoltage, over temperature, overload,and short circuit. It uses a synchronous rectification technique to significantly reduce switching loss and extend product lifetime.

The operating principle of the LNK562DG power supply controller is based on a voltage feedback topology. A rectified AC input is sensed by a comparator and is sent to an internal oscillator. The oscillator is triggered and switches a sense output MOSFET according to the AC input voltage. The rectified voltage is compared to the programmed output DC voltage and when the output falls below the set level for overvoltage protection, the peak current sensing mechanism will shut off the FET switch. This prevents the output from exceeding the programmed set level.

The primary application areas for the LNK562DG power supply controller IC are LCD monitors, televisions, DVD players, and other consumer electronics. Additionally, the device can be used in medical instruments, industrial controllers, and security equipment. This AC/DC controller allows for a simple design and low component cost, so it is ideal for cost-sensitive applications such as the consumer electronics and medical fields.

In summary, the LNK562DG power supply controller is an AC/DC converter IC designed for use in low-cost consumer electronics and medical applications. Its features include an isolated, offline design, low no-load power consumption, wide input voltage range, overvoltage and undervoltage protection, and a synchronous rectification technique. The device is designed to minimize switching losses and extend product lifetime while providing excellent energy efficiency and fast transient response.
