Power Integrations InnoSwitch3-AQ Family

Description
The InnoSwitch.3-AQ family of ICs dramatically simplifies the design and manufacture of isolated flyback power converters in automotive applications. The InnoSwitch3-AQ family combines primary and secondary controllers and safety-rated feedback into a single IC allowing accurate output voltage regulation even with a very wide input voltage range.
InnoSwitch3-AQ family devices incorporate multiple protection features including line overvoltage and undervoltage protection, output overvoltage, over-current limiting, and over-temperature shutdown. Device start-up from 30 V makes InnoSwitch3 parts ideal for emergency power supplies (EPS).
