The Power Integrations TOP222PN is a highly integrated offline switcher IC belonging to 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 start-up circuit, loop compensation, and fault protection circuitry into a single monolithic IC. It supports multiple topologies including Flyback, Forward, Boost, and Buck. Key electrical specifications include a 700V breakdown voltage, 15W maximum output power for single voltage input, and a switching frequency of 100kHz.
The TOP222PN features built-in auto-restart and current limiting, along with latching thermal shutdown for system-level protection. It is suitable for applications requiring high efficiency, with very low AC/DC losses up to 90% efficiency.
Packaged in an 8-PDIP through-hole configuration, this component is designed for easy mounting on PCBs. The operating temperature range is -40°C to 150°C (TJ).
