SY5830 controller equivalent, single stage flyback and pfc controller.
* Primary side control eliminates the opto-coupler.
* Valley turn-on of the primary MOSFET to achieve
low switching losses
* Power factor >0.90 with single-st.
Note: SY5830
Single Stage Flyback And PFC Controller With Primary Side Control For LED Lighting
Preliminary datasheet
G.
The SY5830 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 .
