|InnoSwitch3-CP Data Sheet||2.38 MB|
The InnoSwitch™3-CP family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. The InnoSwitch3-CP family incorporates primary and secondary controllers and safety-rated feedback into a single IC.
InnoSwitch3-CP 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 quick charge and USB PD designs. The devices are available with and without cable-drop compensation.

InnoSwitch-3 Feature Codes
InnoSwitch-3 ICs are highly configurable, and require a "Feature Code" to specify all of the configurable characteristics, such as the Auto Restart Threshold, Fault Response, and others. Feature Codes consist of the letter "H" followed by three numbers and are added to the end of the base part number. A Feature Code is required when ordering parts (e.g., INN3265C-H202).
The tables below provide a list of the characteristics of the Feature Codes, and the parts available with that Feature Code. Please use these to determine which InnoSwitch-3 part is the best fit for your application. Alternatively, you can use our Build Your Own InnoSwitch tool.
