详细说明
General DeSCRJPTion
The SY58203 is a single stage Flyback and PFC regulator targeting at LED lighting applications. It integrates a 700V MOSFET to decrease physical volume 。It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasi-resonant mode to achieve higher efficiency. It keeps the Flyback converter in constant on time operation to achieve high power factor.
Features
* Integrated 700V MOSFET
* Primary side control eliminate to the opto-coupler.
* Valley turn-on of the primary MOSFET to achieve low switching losses
* 0.3V primary current sense reference voltage leads to a lower sense resistance thus a lowerconduction 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: 120kHz
* Compact package: SO8
SY58294
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.
