The LNK574DG is an AC/DC converter designed to support a wide range of applications. It is a highly integrated offline switcher with a peak efficiency of up to 90%, meeting the requirements of Energy Star Level V standby power efficiency. This part includes extensive protections and a flexible output voltage adjustment range. It is suitable to be used in applications like desk top/notebook adapters, consumer appliances and peripherals, telecom power supplies, industrial control systems, and more.

The working principle of the LNK574DG is fairly simple. It is based on the concepts of Buck and Boost voltage regulation. The device converts the AC input voltage to a regulated DC output voltage with a conversion efficiency of up to 90%. The AC input voltage is fed into the AC/DC converter, which first rectifies the AC voltage using a Bridge Rectifier. The rectified voltage is then filtered by an output LC filter, which smoothens out the ripple noise on the output. This regulated DC output is then fed to the output pins.

The LNK574DG also features a wide range of protection features to ensure the safety of the system. It features Under Voltage Lock-Out (UVLO) protection, Automatic Over Current Protection (OPP) and Over Temperature Protection (OTP). It also has an input voltage range of 90V to 264Vac and an output adjustable voltage range of 3.3V to 15Vdc with a maximum output current of 3A. The device integrates a PWM controller and MOSFETs into a single package, providing excellent efficiency and very low power consumption.

The LNK574DG is a high performance AC/DC converter providing very high efficiency, excellent temperature performance, and very low power consumption. It is an ideal solution for applications that require high efficiency, excellent temperature performance and low power consumption. It provides comprehensive protection features and flexible output voltage adjustment range meeting the requirements for Energy Star Level V standby power efficiency.
