The InnoSwitch™ Family of ICs combines primary, secondary and feedback circuits in a single surface-mounted off-line flyback switcher IC. The InnoSwitch IC incorporates a high-voltage primary-side switch, the primary-side controller, a secondary-side controller for synchronous rectification and an innovative new FluxLink™ technology that eliminates the need for an optocoupler.
PowiGaN™ is Power Integrations’ internally developed gallium nitride (GaN) technology. PowiGaN switches replace the traditional silicon transistors on the primary side, reducing switching losses and enabling power supplies that are more efficient, smaller and lighter than silicon alternatives. PowiGaN-based ICs achieve up to 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without requiring a heatsink.
FluxLink™ communication technology enables feedback information to be delivered across an isolation barrier without the use of any magnetic materials. FluxLink delivers a very high communication bandwidth which enables a much faster load-transient response. This proprietary technology meets all global noise immunity standards. For safety, it complies not only with UL and TUV global isolation standards but also the more stringent CQC 5,000 meter Chinese safety standard.
