Applications

Power supplies for automotive subsystems such as the traction inverter

emergency power supply (EPS), high-voltage to low voltage DC/DC

converters (mDCDC) in battery management systems, on-board

chargers and 12 V system standby power supplies.

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-AQ parts ideal for

emergency power supplies (EPS).
