详细说明
General DeSCRJPTion
The SY5800A 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 converter in constant on time operation to achieve high power factor.
Features
* Primary side control eliminates 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 lower conduction loss.
* Internal high current MOSFET driver: 1A sourcing and 2A sinking
*Low start up current: 15μA typical
*Reliable short LED and Open LED protection
*Power factor >0.90 with single-stage conversion.
* Compact package: MSOP10 and SO8
