The SY5839 is a single stage Buck PFC controller targeting at LED lighting applications. 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 fact.
• Valley turn-on of the MOSFET to achieve low switching losses
• Power factor >0.90 with single-stage conversion.
• Low start up current: 15µ A typical
• Quick start up <500ms
• Reliable short LED and Open LED prote.
