Description
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.
