Power Integrations TOPSwitch®-II TOP221P is an 8-Pin PDIP offline switcher IC designed for high-efficiency power conversion. This component supports multiple topologies including Boost, Buck, Flyback, and Forward converters with a switching frequency of 100kHz. It features an integrated switch with a breakdown voltage of 700V and a maximum duty cycle of 67%. The TOP221P offers robust fault protection through internal current limiting and over-temperature shutdown. Operating within an ambient temperature range of -40°C to 150°C (TJ), it is suitable for isolated output applications. This device is commonly utilized in consumer electronics, industrial power supplies, and adapter applications. The TOP221P is supplied in a tube.
