LD7837 Datasheet | Leadtrend

04/06/2017 High Performance Primary Side Flyback LED Controller with HV Start-up REV. 00 General Description The LD7837 is a high performance primary side Flyback or Buck Boost LED Controller with HV start-up special design for LED lighting. This IC operating on transition mode(TM) and integrated with pleted safety requirement protections. It minimizes the ponents counts in a SOP-7 package. Those make it easy design for cost- effective applications. This chip provides High Current Accuracy at full input voltage range form from 85V to 277V Vac. The constant on time PFC control and THDi pensator could easily achieve PF>0.90 and THDi <10% to meet most of the international...
