The INN4674F-H342-TL from Power Integrations is an isolated flyback AC-DC converter with secondary-side synchronous rectification and an integrated 750 V switch. It delivers up to 170 W from an 85–265 VAC input and includes current limiting, over load, over temperature, over voltage, short circuit, and UVLO protection. Soft start and frequency control support stable startup, and the device operates from -40°C to 105°C in a 28-PowerSMD module.
- High power density: 170 W output from universal 85–265 VAC input in a compact PowerSMD module.
- Integrated 750 V switch reduces external component count and simplifies isolated flyback design.
- Secondary-side SR flyback topology improves isolated conversion efficiency.
- Comprehensive fault protection (current limiting, over load, over temperature, over voltage, short circuit, UVLO) enhances reliability.
- Wide -40°C to 105°C operating range supports demanding environments.
