The LNK364GN is a monolithic integrated circuit that combines high-performance full-bridge topology, low on-resistance, low-power loss and low operating current. It is mainly used to provide power to offline switchers and AC/DC converters. The LNK364GN is designed to handle loads up to 600 W and handle peak currents up to 10 A. The high-frequency operation of the device helps to reduce transformer and other passive components size, resulting in a more efficient, lighter and smaller power supply for the products.

The LNK364GN features an adjustable switching frequency from 300 kHz to 1.2 MHz to allow fine tuning of the circuit design for minimum loss and maximum efficiency. The adjustable cycle-by-cycle current limit works in conjunction with the adjustable over-temperature protection to provide reliable and safe operation. There is an additional protection feature in the device that prevents the output voltage from over-voltage when the output load is removed completely.

The LNK364GN is designed with a low quiescent current of 50�A at normal with no-load. This helps to reduce power consumption in stand-by and no-load situations, making it ideal for power-sensitive applications. The device also features a low EMI with a spread spectrum function and an internal soft-start function that reduces start-up stress and inrush current.

The LNK364GN can operate in a variety of topologies, including buck, boost, buck-boost, forward, and flyback. When operating in the buck or boost topologies, the device features a synchronous rectification control to minimise losses, saving energy and increasing efficiency. In addition, the LNK364GN has a programmable current limiting, under-voltage lockout, over-voltage protection, and over-temperature protection for reliable and safe operation.

The LNK364GN is capable of working with high frequency AC/DC converters. Its design allows for miniaturization of transformer and other components, resulting in greater efficiency and cost savings. The low quiescent current and EMI features also help reduce design size. It is also suitable for use in devices with difficult cooling situations, due to its low power loss. Overall, the LNK364GN is an ideal choice for a broad range of applications, such as solar power systems, automotive, building automation, and other similar applications.
