TOP222GN Description

Short technical summary and product information.

The POWER TOP222GN is part of the TOPSwitch-II family, offering a cost-effective and low component count solution for power supplies. This monolithic IC integrates a power MOSFET, PWM controller, high-voltage start-up circuit, loop compensation, and fault protection circuitry.

Key features include built-in auto-restart and current limiting, along with latching thermal shutdown for system-level protection. The device supports various topologies such as Flyback, Forward, Boost, or Buck, and can work with primary or opto feedback. It is stable in both discontinuous and continuous conduction modes.

The TOPSwitch-II family extends the power range, with the TOP222GN capable of delivering up to 45W for universal input (85-265 VAC) and 15W for single voltage input (100/115/230 VAC) when using the TO-220 package. For the 8-pin DIP or SMD packages, it can deliver up to 75W for universal input and 30W for single voltage input.

Designed for ease of use, the TOP222GN reduces sensitivity to board layout and line transients. The internal lead frame utilizes six pins to transfer heat directly to the board, often eliminating the need for a heatsink. This product is suitable for applications like TVs, monitors, and audio amplifiers.
