General Description
The SY58203A1 is a single stage Flyback and PFC regulator targeting at LED lighting applications.
It integrates a 700V MOSFET to decrease physical volume.
Key Features
- Integrated 700V MOSFET.
- Primary side control eliminate to 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.
- Low start up current: 15µA typical.
- Reliable short LED and Open LED protection.
- Power factor >0.90 with single-stage conversion.
- Maximum frequency limit: 120kHz.
