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.
