The Power Integrations TOP227YN is a highly integrated offline switcher IC designed for cost-effective, high-efficiency power supply applications. It incorporates a power MOSFET, PWM controller, and various protection circuits into a single monolithic IC.
This device supports multiple topologies including Flyback, Forward, Boost, and Buck, making it versatile for various designs. It features a 700V breakdown voltage and can deliver up to 150W of power. The built-in auto-restart and current limiting, along with latching thermal shutdown, provide robust system-level protection.
Packaged in a TO-220-3 through-hole configuration, the TOP227YN is designed for ease of mounting. Its internal lead frame aids in heat dissipation, potentially eliminating the need for an external heat sink in lower power applications. The TOPSwitch-II family offers enhancements for reduced sensitivity to board layout and line transients, simplifying the design process and reducing time to market.
Key features include very low AC/DC losses for up to 90% efficiency, a 67% duty cycle, and a switching frequency of 100kHz. The operating temperature range is -40°C to 150°C (TJ).
