The Power Integrations INN4475F-H341-TL is an isolated flyback AC-DC converter with secondary-side synchronous rectification and an integrated 750 V switch. Operating from 85-265 VAC, it delivers up to 180 W and includes current limiting, over load, over temperature, over voltage, short circuit, and UVLO protection. Frequency control and soft-start support stable isolated power designs across a -40°C to 105°C range.
- High power density: 180 W output from a compact 28-PowerSMD module with integrated switch.
- Galvanically isolated flyback with secondary-side SR for simplified isolated designs.
- Robust protection suite: current limiting, over load, over temperature, over voltage, short circuit, and UVLO.
- Wide -40°C to 105°C operating range for demanding environments.
- Frequency control and soft-start for stable startup and operation.
High-Power AC-DC Adapters
The 180 W capability and 750 V integrated switch make this InnoSwitch™4-Pro device well suited for high-power adapters operating from universal 85-265 VAC mains, with secondary-side SR for efficient isolated output.
