The InnoSwitch™3-CE family of ICs dramatically simplifies the designand manufacture of flyback power converters, particularly thoserequiring high efficiency and/or compact size. The InnoSwitch3-CEfamily incorporates primary and secondary controllers and safety-ratedfeedback into a single IC.

　　InnoSwitch3-CE family devices incorporate multiple protection featuresincluding line over and under-voltage protection, output over-voltageand over-current limiting, and over-temperature shutdown. Devices areavailable that support the common combinations of latching andauto-restart behaviors required by applications such as chargers,adapters, consumer electronics and industrial systems. The devices areavailable with and without cable-drop compensation.
