General Description
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.
Key Features
- Primary side control eliminate the opto-coupler.
- Internal high current MOSFET driver: 1A sourcing and 2A sinking.
- Low quiescent current at start up mode: 10uA typical.
- 16V rising UVLO with 9V hysteresis.
- Valley turn-on of the primary MOSFET to achieve low switching loss.
- 0.5V max sense voltage on the primary side to minimize the conduction loss.
- Reliable short LED and Open LED protection.
- Good power factor(>0.90) with sin.
