Design of Dimmable Quasi-Resonant Fly Back LED Driver Based on OZ9992

Abstract:

The paper designs a 30W dimmable constant current LED driver. It is designed by O₂Micros OZ9992 control chip, and it use quasi-resonant flyback topology. It can achieve zero voltage to reduce switching losses. The LED driver has higher efficiency and can provide a stable current for LED lamps. It has good dimming performance, and is easy to operate. It is suitable for home, hotel and other occasions, and has broad application prospects.
