The LNK6779K is a family of AC/DC converters and offline switchers from Power Integrations, Inc. It is designed to provide maximum efficiency and accuracy in managing power delivery within a system. This makes it suitable for a range of applications, including consumer electronics, network systems, and industrial automation. The LNK6779K is made up of two devices: a low-power, high-speed control IC (LNK679IC) and a high-voltage, high-current rated secondary side driver (LNK679S). These two components work together to ensure a speedy, efficient, and accurate control of power delivery. The IC reduces the load current at a specific voltage, enabling accurate power delivery control. Meanwhile, the secondary side driver provides the necessary output voltage, current, and polarity regulation, while also reducing output ripple.The IC has three operating modes – constant voltage, current mode, and constant power mode. The voltage and current settings can be adjusted to achieve the desired power setting. The LNK6779K can also be used in disabling mode, where it automatically pauses operation when a fault is detected. This helps protect the system and its components. The LNK6779K also features a range of protection features. It has a fast over-voltage detection that immediately shuts down the system when it detects an over-voltage condition. Over-temperature protection is also provided, making the device suitable for use in high-temperature environments.In addition, the LNK6779K has a wide range of diagnostic features. Its intelligent safety systems can detect a range of faults, including over-voltage, under-voltage, and over-temperature conditions. It also has a smart current sense interface, providing precise current control.Overall, the LNK6779K is an excellent choice for a range of AC/DC converters and offline switchers. It combines fast speed, accurate control, and versatile protection features, making it a great choice for mission-critical systems. The LNK6779K is suitable for a range of applications, including consumer electronics, network systems, and industrial automation.
