INN4275C-H182

Off-Line CV/CC Flyback Switcher IC with Integrated 750 V PowiGaN Switch, Synchronous Rectification and Quasi-Resonant (QR) Operation

애플리케이션

제품 상세 정보

The InnoSwitch™4-QR family of ICs dramatically improve the efficiency of flyback power converters, particularly those requiring a compact form-factor. The InnoSwitch4-QR family incorporates primary and secondary controllers, PowiGaN power switch and safety-rated feedback (FluxLink) into a single IC.

The InnoSwitch4-QR IC also incorporates multiple protection features including output overvoltage and over-current limiting, and overtemperature shutdown. Devices are available that support combinations of latching and auto-restart protection modes typically required for applications such as chargers, adapters, consumer electronics and industrial systems.
