    SY22664 is a single-stage driver for LED lighting applications.

     

    SY22664 adopts proprietary techniques to identify whether dimmer applied and dimmer types. Good compatibility is achieved with Leading/Trailing edge dimmer and high PF is achieved without any dimmer.

     

    SY22664 drives the converter in Quasi-Resonant mode to achieve high efficiency. Reliable Open/Short LED protections are integrated.

     

    SY22664 is available in SO8 package.
