TOP222Y Converter Offline Boost, Buck, Flyback, Forward Topology 5.7V 1.2mA TO-220-3 The TOP222Y is part of the TOPSwitch family of integrated power conversion ICs, designed for offline switch-mode power supplies. It combines a high-voltage power MOSFET, PWM controller, oscillator, and protection circuitry into a single compact device. This integration significantly reduces external component count and simplifies circuit design, making it a popular choice for cost-effective and reliable power supply solutions. This IC supports multiple topologies including boost, buck, flyback, and forward converters, giving designers flexibility in various applications. It operates directly from rectified AC mains and features intelligent control mechanisms such as auto-restart, thermal shutdown, and line protection. Its TO-220-3 package allows efficient heat dissipation, making it suitable for medium power applications like adapters, chargers, and consumer electronics power supplies.
