SD7860
PRIMARY SIDE REGULATED CONSTANT CURRENT LOW PFC ISOLATED FLYBACK CONTROLLER FOR LED DRIVER

    The SD7860 is a primary side regulated constant current low PFC isolated flyback controller, it has a built-in high voltage power MOSFET, is used together with a pre-stage APFC boost circuit to achieve two stage isolated no flicker application.

    The SD7860 provides accurate constant current control and operates in boundary conduction mode (BCM). The Device adopts primary side regulation eliminating the opto-couple for simplifying design and reducing cost.

    The SD7860 provides complete protections such as short LED protection, open LED protection and over temperature protection, etc.
