SY5800A - Single Stage Flyback And PFC Controller
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 Flybac
SY5800A 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 dri
