SY5800 - Single Stage Flyback And PFC Controller
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 factor applications.
