Off-Line CV/CC QR Flyback Switcher IC with Integrated Primary Switch,Synchronous Rectification, FluxLink Feedback and Constant Power Profile.The InnoSwitch3-CP family of ICs dramatically simplifies the designand manufacture of flyback power converters, particularly thoserequiring high efficiency and/or compact size. The InnoSwitch3-CPfamily incorporates primary and secondary controllers and safety-rated

feedback into a single IC.

InnoSwitch3-CP family devices incorporate multiple protection featuresincluding line over and undervoltage protection, output overvoltageand over-current limiting, and over-temperature shutdown. Devices areavailable that support the common combinations of latching andauto-restart behaviors required by applications such as quick chargeand USB PD designs. The devices are available with and withoutcable-drop compensation.
