TOP224G Description

Short technical summary and product information.

The Power Integrations TOP224G is a highly integrated offline switcher IC designed for cost-effective, low-component-count power supply solutions. It incorporates a power MOSFET, PWM controller, high-voltage start-up circuit, loop compensation, and fault protection circuitry into a single monolithic IC.

 

This device operates with a voltage rating of 700V and a frequency of 100kHz, delivering up to 30W of power. It supports multiple topologies including Boost, Buck, Flyback, and Forward, and offers isolated output. The internal switch functionality simplifies design and reduces component count.

 

Packaged in an 8-SMD, Gull Wing configuration, the TOP224G is designed for surface mount applications. It features built-in auto-restart and current limiting, along with latching thermal shutdown for system-level protection. Its operating temperature range is -40°C to 150°C (TJ).
