Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - TOP221G TOP221G

The TOP221G is part of the TOPSwitch-II family of offline PWM switches designed for AC to DC conversion. It features a three-terminal configuration and is capable of implementing various topologies, including Flyback, Forward, Boost, and Buck. The device operates efficiently with up to 90% efficiency and supports a power range of 10W to 15W for single voltage input applications at 100/115/230 VAC. Key features include built-in auto-restart, current limiting, and latching thermal shutdown for enhanced system protection. The internal design integrates a power MOSFET, PWM controller, high-voltage startup circuit, and fault protection circuitry, which simplifies circuit design and reduces component count. The package options include TO-220, DIP-8, and SMD-8, with a source-connected tab to minimize electromagnetic interference (EMI). This product is suitable for applications such as televisions, monitors, and audio amplifiers, making it a versatile choice for engineers looking for a reliable and efficient power conversion solution.
