INN3168C-H109
Off-Line CV/CC QR Flyback Switcher IC with Integrated 650 V MOSFET, Synchronous Rectification & FluxLink Feedback for Applications up to 65 W
Product Details
The InnoSwitch3-CE family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. The InnoSwitch3-CE family incorporates primary and secondary controllers and safety-rated feedback into a single IC.
InnoSwitch3-CE family devices incorporate multiple protection features including line over and under-voltage protection, output over-voltage and over-current limiting, and over-temperature shutdown. Devices are available that support the common combinations of latching and auto-restart behaviors required by applications such as chargers, adapters, consumer electronics and industrial systems. The devices are available with and without cable-drop compensation.
