INN3278C-H114-TL, AC/DC Converters Off-Line CV/CC 75W 750V FET PowiGaN (GaN)

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. This 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 overcurrent limiting and overtemperature shutdown. Incorporates quasi-resonant (QR) / CCM flyback controller, high-voltage switch, secondary-side sensing and synchronous rectification driver. Constant power profile minimizes charging time with continuous adjustment of output current and voltage. Devices are available that support common combinations of latching and auto-restart behaviours required by applications such as high efficiency flyback designs up to 100W and USB PD / QC / proprietary protocol chargers.
