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 completed safety
requirement protections. It minimizes the components
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 compensator could easily
achieve PF>0.90 and THDi <10% to meet most of the
international standard requirements.
With completed protection built inside this IC, such as
over voltage protection (OVP), over current protection
(OCP) and short circuit protection (SCP), it enables the
circuit to meet most safety requirements in both normal
and abnormal test.
