LD7838 High Power Factor Flyback LED Controller

LD7838 Description

LD7838 11/22/2016 High Power Factor Flyback LED Controller with HV Start-up REV.01 General .
The LD7838 is a 700V HV start-up active PFC Flyback controller, specially designed for LED lighting application.

LD7838 Features

* High voltage (700V) startup circuit by HV pin for 85~305VAC input range
* High Power Factor ( > 0.92)
* High-efficiency Transition mode operation
* Lower Power Saving ( < 0.5W)
* Accurate OLP Compensation for High/ Low Line
* Built in BNI/ BNO Function
* Wide UVLO (16Vo

LD7838 Applications

* With High Voltage start-up technology, power factor correction and boundary mode switching control, the start-up time and resistor loss could be minimized efficiently. The circuit can easily achieve power factor is upper 0.92 to meet most of the international requirements as IEC61000-3-2 standard c
