The Power Integrations INN4474F-H341-TL is an isolated flyback AC-DC converter with secondary-side synchronous rectification, delivering 170 W from an 85–265 VAC input. It integrates the power switch with a 750 V breakdown rating and includes current limiting, over load, over temperature, over voltage, short circuit, and UVLO protection. Soft start, enable, and frequency control simplify design, while the -40°C to 105°C range supports demanding applications.
- Integrated 750 V switch reduces external component count in isolated flyback designs.
- Secondary-side SR improves efficiency in the isolated output stage.
- Comprehensive fault protection (over load, over temperature, over voltage, short circuit, UVLO) enhances reliability.
- Wide -40°C to 105°C operating range suits industrial and demanding environments.
- Soft start and frequency control ease startup and EMI-conscious design.
High-Power AC-DC Adapters
At 170 W from universal 85–265 VAC input, the flyback topology with secondary-side SR suits higher-power isolated adapters for laptops, docking stations, and power tools.
Industrial and Telecom Supplies
The -40°C to 105°C range and full fault protection set (over load, over temperature, over voltage, short circuit, UVLO) support robust isolated supplies in industrial and communications equipment.
Appliance Power
Integrated switch and soft start reduce external parts, easing design of isolated offline supplies for major appliances up to 170 W.
Display and Audio Power
Frequency control and enable features allow flexible regulation in isolated power stages for displays, soundbars, and AV equipment.
Charging and Battery Systems
Secondary-side SR and comprehensive protection make this device suitable for isolated chargers and battery-backed systems.
