Power Integrations TOPSwitch®-II TOP221G is an 8-SMD, gull wing surface mount offline switcher IC. This component integrates a high voltage MOSFET and control circuitry, enabling efficient power conversion across Boost, Buck, Flyback, and Forward topologies. It features internal switching capabilities and operates at a nominal switching frequency of 100kHz. The device offers robust fault protection, including current limiting and over-temperature protection, with a maximum breakdown voltage of 700V. Designed for applications requiring up to 9W of power, the TOP221G is suitable for use in consumer electronics, industrial power supplies, and adapter markets. Its insulated output is provided in a tube package.
