LD7833
LD7833 is High Power Factor Primary Side Flyback LED Controller manufactured by Leadtrend Technology.
Description
The LD7833 is a primary side regulation Flyback controller with power factor for TRIAC dimmable LED driver. The LD7833 provides constant current (CC) operation requiring neither photo-coupler nor secondary control circuit. It minimizes the ponents counts in a tiny package. Those make it easy to design for costeffective applications.
With high voltage start-up technology, high power factor and TM control, the start-up time and MOSFET switching losses could be minimized efficiently.
With pleted protection built in this IC, such as overvoltage protection (OVP), over-current protection (OCP) and short circuit protection (SCP), the device is capable to meet the safety requirements.
