TNY286KG is a high integration, low-cost, offline, AC/DC converter IC manufactured by Power Integrations, specially designed for small power supplies used in lighting, TV and appliances. Its application fields include SMPS, LED lighting and adapters. Its main features are low junction temperature, high efficiency, and high EMI performance. The device is designed using an advanced FluxLink fully integrated magnetics technology featuring low-loss Si-core transformers. This article will discuss the application fields, working principle and main features of the TNY286KG. #### Application FieldsTNY286KG has a wide range of application fields, most notably high-efficiency power supplies used in SMPS (switch-mode power supplies). It is designed to provide high-efficiency solutions while being relatively inexpensive and easy to use. The device also features low junction temperature and high EMI performance, allowing for the applications of the device across a wide range of different industries. Additionally, the device is suitable for use with LED lighting systems, which are becoming increasingly popular due to their energy efficiency and long lifetime. Lastly, the device is also suitable for use in adapter supplies for computers and other electrical appliances.#### Working PrincipleTNY286KG is based on a FluxLink fully integrated magnetics technology that uses low-loss Si-core transformers. The device utilizes a two-stage converter, with an auxiliary winding that provides isolation and a primary winding that allows for current flow. The auxiliary winding is powered by a capacitor, with rectified AC voltage applied directly to the primary winding. A high-speed synchronous switch is then used to regulate the flow of power from the primary winding. Through the use of the synchronous switch, the device is able to convert the AC voltage into DC voltage, allowing for efficient conversions with minimal power loss.#### Main FeaturesOne of the main benefits of TNY286KG is its low junction temperature. It is able to supply up to 12W of power with a junction temperature of 60°C, allowing for efficient operation in a wide range of temperatures. Additionally, the device is designed to be highly efficient, with a typical efficiency of greater than 90%. This allows for minimal power loss, reducing total energy consumption and improving overall performance. Finally, the device also has high EMI performance, allowing for its use in noise-sensitive environments. This is due to the use of advanced FluxLink technology, which is able to greatly reduce EMI interference.Overall, the TNY286KG is a highly integrated, low-cost, offline, AC/DC converter IC specially designed for small power supplies used in lighting, TV and appliances. The device is suitable for use in a wide range of applications, such as SMPS, LED lighting and adapters. Its main features are low junction temperature, high efficiency, and high EMI performance, making it an ideal choice for use in sensitive noise environments.
