The InnoSwitch™3-EP family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. The InnoSwitch3-EP family combines primary and secondary controllers and safety-rated

feedback into a single IC.

InnoSwitch3-EP 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 with standard and peak power delivery options, and commonly used auto-restart protection behaviors.
