Power Integrations InnoSwitch3-AQ Family of ICs

Simplify your design and manufacturing of flyback power converters

The InnoSwitch3-AQ family by Power Integrations combines primary and secondary controllers and safety-rated feedback into a single IC allowing accurate output voltage regulation even with wide input voltage range of 30 VDC to 1000 VDC.

This family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size.

InnoSwitch3-AQ family devices incorporate multiple protection features including line over and undervoltage protection, output overvoltage and over-current limiting, and over-temperature shutdown for automotive applications. Device start-up from 30 V makes it ideal for functional safety critical emergency power supplies.
