Single Stage Flyback And PFC Controller With Primary Side Control For LED Lighting

The SY5840 is a single stage Flyback and 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 • Primary side control eliminates the opto-coupler.\r\n• Valley turn-on of the primary MOSFET to achieve low switching loss\r\n• Power factor >0.90 with single-stage conversion.\r\n• Reliable short LED and Open LED protection\r\n• Quick start up <500ms\r\n• Low start up current:15µA typical\r\n• Pac;
