The INN4775C-H191-TL from Power Integrations is an isolated offline AC/DC switcher using Flyback topology with secondary-side synchronous rectification. It integrates the power switch with a 750V breakdown rating and operates from an 85V to 265V Vcc supply, delivering up to 180 W at 50kHz to 140kHz switching frequency. Current limiting, over-temperature, over-voltage, and UVLO protection plus soft start support dependable designs across a -40°C to 105°C ambient range in a 24-PowerSMD module.
- Flyback topology with secondary-side SR for isolated, efficient power conversion.
- Integrated 750V switch simplifies primary-side design.
- 180 W output supports higher-power isolated applications.
- Comprehensive protection (current limiting, OVP, OTP, UVLO) improves reliability.
- Wide 85V to 265V Vcc range and -40°C to 105°C ambient rating suit diverse environments.
