SY5800 controller equivalent, single stage flyback and pfc controller.
* Primary side control eliminate the opto-coupler.
* Internal high current MOSFET driver: 1A sourcing
and 2A sinking
* Low quiescent current at start up mode:.
It receives the rectified AC input voltage up to 400V, and drives the Flyback converter in a quasi-resonant mode for hi.
The SY5800 is a single stage Flyback and PFC controller that targets at LED lighting applications. It receives the rectified AC input voltage up to 400V, and drives the Flyback converter in a quasi-resonant mode for high efficiency unified power fac.
