The SD782XD 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 SD782XD 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 SD782XD provides complete protections such as short LED protection, open LED protection and over temperature protection, etc.
