Description

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 undervoltage protection, output overvoltage

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.
