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.
