Applications

• High density flyback designs up to 220 W

• High efficiency CV/CC power supplies

• High efficiency USB PD adapters

Description

The InnoSwitch™4-QR family of ICs dramatically improve the efficiency

of flyback power converters, particularly those requiring a compact

form-factor. The InnoSwitch4-QR family incorporates primary and

secondary controllers, PowiGaN power switch and safety-rated

feedback (FluxLink) into a single IC.

The InnoSwitch4-QR IC also incorporates multiple protection features

including output overvoltage and over-current limiting, and overtemperature

shutdown. Devices are available that support combinations

of latching and auto-restart protection modes typically required for

applications such as chargers, adapters, consumer electronics and

industrial systems.
