TNY285DG Description

Short technical summary and product information.

The TNY285DG from Power Integrations is part of the TinySwitch-4 family of energy-efficient, off-line switchers. This IC features a 725V rated MOSFET, increasing de-rating margin and providing line-compensated overload power without additional components. It offers selectable current limits for optimizing efficiency in enclosed adapters or extending peak power in open frame applications.

 

Designed for Flyback topology, the TNY285DG operates with an output power of 8.5W. It includes essential fault protection features such as current limiting, open loop, over temperature, over voltage, and short circuit protection. The device also incorporates hysteretic thermal shutdown with automatic recovery and auto-restart for enhanced reliability.

 

This IC is housed in an 8-SOIC package with surface mount capability. The operating temperature range is -40°C to 150°C (TJ). Its frequency ranges from 124kHz to 140kHz, with a duty cycle of 67%.
