The Power Integrations INN4777C-H191-TL is an offline AC-DC converter using a flyback topology with secondary-side synchronous rectification. It integrates a 750 V switch and delivers up to 220 W from an 85-265 VAC input with a 50 kHz to 140 kHz switching frequency. Galvanically isolated and protected against over temperature, over voltage, current limiting, and UVLO, it operates from -40°C to 105°C.
- High 220 W output from universal 85-265 VAC input for high-power offline designs.
- Integrated 750 V switch reduces external components and simplifies the flyback stage.
- Secondary-side synchronous rectification supports efficient isolated conversion.
- Frequency control (50 kHz to 140 kHz) and soft-start enable flexible design tuning.
- Fault protection and -40°C to 105°C range enhance reliability in demanding environments.
