TOP222PN Description

Short technical summary and product information.

The Power Integrations TOP222PN is a highly integrated offline switcher IC from the TOPSwitch-II family. It is designed for cost-effective, low-component-count power supply solutions.

 

This device incorporates a power MOSFET, PWM controller, high-voltage startup circuit, loop compensation, and fault protection circuitry into a single monolithic IC. Key electrical specifications include a breakdown voltage of 700V, a switching frequency of 100kHz, and a duty cycle of 67%. It supports multiple topologies including Boost, Buck, Flyback, and Forward.

 

The TOP222PN offers various power output capabilities depending on the input voltage and configuration, ranging up to 150W for 100/115/230 VAC input and up to 90W for universal 85-265 VAC input. It includes built-in auto-restart and current limiting, along with latching thermal shutdown for system-level protection.

 

Packaged in an 8-PDIP through-hole configuration, the TOP222PN is suitable for applications requiring efficient AC/DC conversion. Its design simplifies circuit implementation and reduces time to market.
