INN4276C-H181
Off-Line CV/CC Flyback Switcher IC with Integrated 750 V PowiGaN Switch, Synchronous Rectification and Quasi-Resonant (QR) Operation
製品詳細
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.
