LD7833 controller equivalent, high power factor primary side flyback led controller.
* High Voltage (700V) Startup Circuit
* Transition Mode Operation
* High Power Factor
* Dimmable by TRIAC dimmer
* VCC Over Voltage Pr.
With high voltage start-up technology, high power factor and TM control, the start-up time and MOSFET switching losses .
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 components.
