SY22634A is a single-stage driver for LED lighting applications.
SY22634A 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.
SY22634A drives the converter in Quasi-Resonant mode to achieve high efficiency. Reliable Open/Short LED protections are integrated.
SY22634A integrates high voltage power FET inside to save driver space further.
SY22634A is available in SO8 package.
