Additional preview pages of the SY58203A1 datasheet.

The SY58203A1 is a single stage Flyback and PFC regulator targeting at LED lighting applications.

It integrates a 700V MOSFET to decrease physical volume.

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.
