INN4675F-H342-TL - InnoSwitch4-Pro AC-DC Converter IC

The INN4675F-H342-TL from Power Integrations is a high-performance isolated flyback converter IC from the InnoSwitch™4-Pro family, designed for AC-DC power conversion applications up to 180W. This advanced power management IC integrates secondary-side synchronous rectification (SR) for enhanced efficiency and features comprehensive fault protection including current limiting, over-temperature, over-voltage, short circuit, and UVLO protection.

Engineered for universal input applications, this converter IC operates across a wide 85V to 265V AC input range with a 750V breakdown voltage rating. The device includes intelligent control features such as enable (EN), frequency control, and soft-start functionality, making it ideal for industrial power supplies, consumer electronics, and telecommunications equipment requiring reliable, efficient power conversion.

Available in a compact surface-mount InSOP-T28D package (28-PowerSMD Module) with tape and reel packaging for automated assembly, the INN4675F-H342-TL operates reliably across an extended temperature range of -40°C to 105°C (TA) and is fully RoHS compliant for environmental compliance.
