SY58294 - 15W Single Stage Buck PFC Regulator

Description

The SY58294 is a 15W single stage Buck PFC controller targeting at LED lighting applications.

It integrates a MOSFET with 500V breakdown voltage.

It integrates a 500V MOSFET to decrease physical volume.

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: 15ȝA typical.
  • Reliable short LED and Open LED protection.
  • Power factor >0.90 with single-stage conversion.
  • Maximum frequency limit: 200kHz.
  • Compact package: SO8.

Applications Note:SY58294 15W Single Stage Buck PFC Regulator For LED Lighting Preliminary datasheet General Description The SY58294 is a 15W single stage Buck PFC controller targeting at LED lighting applications. It integrates a MOSFET with 500V breakdown voltage. It integrates a 500V MOSFET to decrease physical volume. It adopts the proprietary control architecture to achieve an accurate primary side 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.
