LD7838H controller equivalent, high power factor flyback led controller.
* High voltage (700V) startup circuit for 305VAC
* High Power Factor Flyback PFC controller
* High-efficiency Transition mode operation
* Low Operation Cu.
With HV start-up technology, high power factor and TM control, the start-up time and resistor loss could be minimized .
The LD7838H is a 700V HV start-up flyback PFC controller, specially designed for LED lighting. This device operates in transition mode(TM) and integrates with completed protections required. It minimizes the components counts in either SOP-7 package..
