The Power Integrations INN4374F-H341-TL is an isolated flyback AC-DC converter with secondary-side synchronous rectification, delivering 90 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 and simplifies isolated flyback design.
- Secondary-side SR improves conversion 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 EMI-conscious design and startup behavior.
