Power Integrations InnoSwitch ICs

FluxLink communication technology enables feedback information to be delivered across an isolation barrier without the use of magnetic materials. FluxLink delivers a very high communication bandwidth, which enables a much faster load-transient response. In addition, FluxLink is highly reliable and does not suffer from the typical optocoupler degradation mechanisms. FluxLink is embedded into the package and thereby eliminates the need for bulky optocouplers. Because it saves space and increases power density, the technology is particularly beneficial for adapters and chargers. Furthermore, this proprietary technology meets all global noise immunity standards. For safety, FluxLink complies with UL and TUV global isolation standards as well as the more stringent CQC 5000 meter Chinese safety standard.

InnoSwitch™3 flyback switcher ICs dramatically simplify the development and manufacturing of low-voltage, high current power supplies. These ICs incorporate both primary and secondary controllers, with sense elements and safety rated feedback mechanism (FluxLink) into a single IC. The Innoswitch™3 ICs feature Integrated MOSFET synchronous rectification and Fluxlink feedback constant voltage and constant current (CC/CV). These ICs ensure high efficiency across the load range through close component proximity and innovative use of the integrated communication link.
