TNY280GN Description

Short technical summary and product information.

The Power Integrations TNY280GN is an energy-efficient, off-line switcher belonging to the TinySwitch-III family. This device is designed for flyback topology and features a 700V voltage rating with an operating frequency of 132kHz. It offers selectable current limits for enhanced flexibility, allowing for optimization in various adapter and open-frame applications.

 

This component provides multiple fault protection features, including current limiting, open loop, over temperature, over voltage, and short circuit protection. It has a duty cycle of 65% and is housed in an 8-SMD (7 leads), Gull Wing package, suitable for surface mounting.

 

The TNY280GN is capable of delivering up to 36.5W peak power in open-frame designs at 230 VAC ± 15% and up to 28.5W in open-frame designs at 85-265 VAC. In enclosed adapter configurations, it provides up to 20W at 230 VAC ± 15% and 14W at 85-265 VAC, measured at +50°C ambient.

 

With its integrated switch and self-biased operation, the TNY280GN simplifies circuit design and reduces component count, enhancing reliability. Its operating temperature range is -40°C to 150°C (TJ).
