General DeSCRJPTion
The SY58294 is a 15W single stage Buck PFC controller targeting at LED lighting applications. It integrates a 500V MOSFET to decrease physical volume. It adopts the proprietary control architecture to achieve an accurate regulation of LED current, unity power factor, and quasi-resonant valley turn-on high efficiency operation.
It integrates open/short LED protection and eliminates the need for opto-coupler, thus minimizing the component count and board size.
Features
* Integrated 500V MOSFET
* Valley turn-on of the MOSFET to achieve low switching losses
* 0.3V current sense reference voltage leads to a lower sense resistance thus a lower conduction loss
* Low start up current: 15μA typical
* Reliable short LED and Open LED protection
* Power factor >0.90 with single-stage conversion.
*Maximum frequency limit: 200kHz
*Compact package: SO8
