The Power Integrations TOPSwitch®-II series TOP221Y is a highly integrated offline switching converter IC designed for efficient power conversion across multiple topologies including Boost, Buck, Flyback, and Forward. Featuring an internal 700V power MOSFET, this component simplifies power supply design by integrating control circuitry and a power switch into a single TO-220-3 package. It operates at a switching frequency of 100kHz with a maximum duty cycle of 67%. Built-in fault protection mechanisms include current limiting and over-temperature shutdown, enhancing system reliability. The TOP221Y is suitable for applications requiring isolated outputs and is commonly employed in consumer electronics, industrial automation, and appliance power supplies. This device is available in a Through Hole mounting type.
