TOP222YN Description

Short technical summary and product information.

The Power Integrations TOP222YN is a versatile AC/DC converter and offline switch IC. It is designed for applications requiring efficient power conversion, offering a voltage rating of 700V and a maximum power dissipation of 25W. The device operates at a switching frequency of up to 110kHz, supporting various topologies including Boost, Buck, Flyback, and Forward.

 

This IC integrates essential functions for a switched-mode control system, including a power MOSFET, PWM controller, and fault protection circuitry. It features built-in auto-restart and current limiting, along with latching thermal shutdown for system-level protection. The TO-220-3 package with through-hole mounting is suitable for direct board integration.

 

The TOPSwitch-II family, to which the TOP222YN belongs, extends power ranges for both universal and single voltage inputs, making it suitable for applications like TVs, monitors, and audio amplifiers. Its design enhancements reduce sensitivity to board layout and line transients, simplifying the design process and reducing time to market.
